Previously stacking contexts were only painted in steps 3, 8, and 9.
These steps are only meant to cover positioned elements (as per
https://www.w3.org/TR/CSS22/zindex.html). This meant that elements with
opacity (which forms a stacking context) could end up painted above
elements that actually occlude them.
This patch removed some previously unsupported scanf format specifiers.
We still don't support these properly, but we can parse and ignore
them, which is equivalent to what this patch was doing.
This is taking over 4 minutes to run on CI, and checks only a dozen
manpages, which is of limited benefit.
Leaving the manpage-generation code in place for now.
We were still missing the resources and the libraries inside the actual
bundle directory. Do it at install time to not make a mess of all the
rules. The gn build lists all the libraries in a massive list, which
is quite a pain. We can over-copy a few libraries like this to make the
install script a bit easier to follow.
The ref tests runner takes screenshots of both the input page and the
expected page, then compares them. Ref testing allows us to catch
painting bugs, which cannot be detected with the layout and text tests
we already have.
With ref tests, we'll likely want to reuse the same expectation page
for multiple inputs. Therefore, there's a `manifest.json` file that
describes the relationship between inputs and expected outputs.
The web specs do not expect decoding or decoding to happen when calling
these helpers. This allows us to remove the raw_fragment helper function
from the URL class.
These cases were found with GCC's `-Wsuggest-final-{types,methods}`
warnings, which catch calls that could have been devirtualized had we
declared the functions `final` in the source.
To reproduce, Link Time Optimization needs to be enabled. The easiest
way to achieve this is to set the `CMAKE_INTERPROCEDURAL_OPTIMIZATION`
cache variable to `ON`. The `.incbin` directive in LibCompress' Brotli
decompressor might needs to be changed to an absolute path for this to
work.
This commit also removes a pair of unused virtual functions.
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
