When audio begins playing, add a button to the left of the favicon with
a speaker icon to indicate which tab is playing audio. This button is
currently disabled, but in the future may be used to mute the tab.
This ensures we consistently show a favicon and that we update the title
to at least display the page URL when there isn't a <title> tag. We
would otherwise continue displaying the previous page's title.
An action icon will be a button-like component to the left of the tab
icon. This initial patch just adds support for rendering an icon. In
the future, we will want to accept an action to be triggered when the
action icon is clicked, and to paint the icon like a button.
Most browsers have some indicator when audio is playing in a tab, which
makes it easier to find that tab and mute unwanted audio. This adds an
IPC to allow the Ladybird chromes to do something similar.
When the command line consists of only whitespace characters, the auto
formatter basically tries to trim the trailing whitespace. But due to a
subtle bug of decrementing an iterator (which is an unsigned integer)
past 0 (or the start of the buffer), that operation resulted in an index
out of bounds error and a crash.
For the normal non-test use case of headless-browser, the function
`load_page_for_screenshot_and_exit()` didn't actually load the requested
webpage in the `WebView`, resulting in an all white pixels screenshot.
I found this interesting, and it also explains e.g. why some
of the step numbers in 6.4 Text Region Decoding Procedure are off --
they added step 3) for COLEXTFLAG and forgot to update step references
to later steps.
Although the flex algorithm as specified does say to determine the cross
size of the flex container, this is not how our layout engine works.
The parent formatting context is responsible for sizing its children,
and since that's already happening, we can simply remove the cross
sizing step from FFC.
If a box has definite width and a preferred aspect ratio, we can
determine its height without performing layout. Hence, its height should
also be considered definite. And the other way around for width from
height as well.
This is preparation for the next commit, which will make flex layout
relinquish control of the flex container cross size to the parent
formatting context.
This way we can just leave it alone if the property hasn't changed.
Notably, if the play-state property has been set to 'paused', and then
the user gets the animation with JS and calls .play() on it, it should
start playing despite the play-state property value.
This adds a test for the code added in #23710.
I created this file using `jbig2` (see below for details), but as
usual it required a bunch of changes to it to make it actually produce
spec-compliant output. See the PR adding this image for my local diff.
I created the test image file by running this shell script with
`jbig2` tweaked as described above:
#!/bin/bash
set -eu
S=Tests/LibGfx/test-inputs/bmp/bitmap.bmp
# See make-symbol-jbig.sh (the script in #23659) for the general
# setup and some comments. See also make-symbol-textrefine.sh (in
# #23713).
#
# `-Ref` takes 5 arguments:
# 1. The symbol ID of this symbol (like after a `-Simple`)
# 2. A bmp file that the base symbol gets refined to
# 3. The ID of the base symbol
# 4. dx, dy

This is in line with what the spec states, the previous implementation
excluded the case where the original message's length is a multiple of
block_size, which would lead to a full block of padding.
We were off-by-one when returning the result of parsing a quoted string
in Web::Fetch::Infrastructure::collect_an_http_quoted_string. Instead of
backtracking the lexer and consuming the backtracked string, do a simple
substring operation.
We have been dancing around circular dependencies between LibCore and
generated sources. For example, LibURL currently cannot depend on
LibUnicode because the LibUnicode generators depend on LibCore, and
LibCore depends on LibURL. LibTimeZone is in a similar situation.
To alleviate this, we can define the minimal sources that the code
generators need as an object library. This will allow the generators to
depend on this library, rather than the full LibCore.
Since the introduction of `AbortSignal::any()`, the specification says
`AbortSignal::create_dependent_abort_signal()` should be used where
`AbortSignal::follow` was previously.
