Removes code that accounts for clip frame's own overflow clip, because
it happens anyway on a first iteration of a loop through containing
blocks chain.
This change causes HTTP status codes to be set on cached HTTP responses.
Otherwise, without this change, no status codes at all are set on cached
HTTP responses — which causes all cached responses to default to being
loaded/served with a 200 status code. And as a result of that, if the
cached response is from a 30x redirect, then without this change, when
that cached 30x response is loaded, we don’t follow the redirect —
because we see a 200 status, rather than the expected/original 30x.

Note that this change also reverts the temporary workaround added in
https://github.com/LadybirdBrowser/ladybird/commit/f735c464d3f
(https://github.com/LadybirdBrowser/ladybird/pull/899).
If a HTTP 401 response we get does not contain a `WWW-Authenticate`
header, we should not trigger the logic to ask the user for credentials
and retry the request.
This part is hinted at in a TODO / 'Needs testing' remark in the spec
but needs to be fleshed out. Raised an upstream issue to do so:
https://github.com/whatwg/fetch/issues/1766
This fixes login forms triggering an infinite fetch loop when providing
incorrect credentials.

The `start` and `end` value set the text alignment based on the computed
value of `direction`. The default value of `text-align` is now `start`
instead of `left`.
If given, the spec expects the input URL to be manipulated on the fly
as it is being parsed, and may ignore any errors thrown by the URL
parser.
Previously, we were not exactly following the specs assumption here
which resulted in us needed to make awkward copies of the URL in these
situations.
For most cases this is not an issue. But it does cause problems for
situations where URL parsing would result in a failure (which is
ignored by the caller), and the URL is _partially_ updated
while parsing.
Such a situation can occur when setting the host of an href alongside a
port number which is not valid. It is expected that this situation will
result in the host being updates - but not the port number.
Adjust the URL parser API so that it mutates the URL given (if any), and
adjust the callers accordingly.
Fixes two tests on https://wpt.live/url/url-setters-a-area.window.html
Currently, the following test case will actually copy both `a` and `b`
when the test macro is expanded:
ByteBuffer a = { some large buffer };
ByteBuffer b = { some other buffer };
EXPECT_EQ(a, b);
This patch redefines the expectation macros to avoid copying.
Because the type returned by to_string is a String, _not_ an
Optional<String>, the following code:
if (serialized_query.is_empty())
serialized_query = {};
Was achieving nothing at all! Make sure that the type is an
Optional<String> so that we're not just setting an empty string to an
empty string.
Quick sort is not a stable sort. This meant we had a subtle issue
implementing this portion of the spec comment:
> The relative order between name-value pairs with equal names must
> be preserved.
Switch to insertion sort which is a stable sort, and properly handles
keys which are the same.

Before this change AddClipRect was a "special" because it didn't respect
scroll frame offset and was meant to be recorded using viewport-relative
coordinates. The motivation behind this was to record a "final" clip
rectangle computed by intersecting all clip rectangles used by a clip
frame. The disadvantage of this approach is that it blocks us from
implementing an optimisation to reuse display list if the only change is
in the scroll offset, because any scroll offset change leads to
invalidating all AddClipRect items within a list.
This change aligns AddClipRect with the rest of display list items by
making it account for scroll frame offset. It required discontinuing
the recording of the intersection of all clip rectangles within a clip
frame and instead producing an AddClipRect for each of them.
A nice side effect is the removal of code that shifts clip rectangle by
`enclosing_scroll_offset()` in a bunch of places, because now it happens
automatically in `DisplayList::apply_scroll_offsets()`.
This change causes the viewport to be treated as a "scroll frame,"
similar to how it already works for boxes with "overflow: scroll."
This means that, instead of encoding the viewport translation into a
display list, the items will be assigned the scroll frame id of the
viewport and then shifted by the scroll offset before execution. In the
future it will allow us to reuse a display list for repainting if only
scroll offset has changed.
As a side effect, it also removes the need for special handling of
"position: fixed" because compensating for the viewport offset while
painting or hit-testing is no longer necessary. Instead, anything
contained within a "position: fixed" element is simply not assigned
a scroll frame id, which means it is not shifted by the scroll offset.
This fixes a crash using URLSearchParams when provided a percent encoded
string which does not percent decode to valid UTF-8.

There are (currently) no spec-tests ensuring that section ordering is
enforced, but it _is_ a part of the spec. A pull request to add this to
the specification testsuite has been opened at WebAssembly/spec#1775.
While introducing clip and scroll frame trees, I made a mistake by
assuming that the paintable tree includes boxes from nested navigables.
Therefore, this comment in the code was incorrect, and clip/scroll
frames were simply not assigned for iframes:
// NOTE: We only need to refresh the scroll state for traversables
// because they are responsible for tracking the state of all
// nested navigables.
As a result, anything with "overflow: scroll" is currently not
scrollable inside an iframe
This change fixes that by ensuring clip and scroll frames are assigned
and refreshed for each navigable. To achieve this, I had to modify the
display list building process to record a separate display list for each
navigable. This is necessary because scroll frame ids are local to a
navigable, making it impossible to call
`DisplayList::apply_scroll_offsets()` on a display list that contains
ids from multiple navigables.
