time, so every error will be different. Printing the line as an info

Right now, the vertical position of the status panel is the "auto"
position, which ends up working out, but mostly by chance, and relies on
behavior that's different from the standard flexbox, see bug 1789165.

Instead of using `position: fixed` and relying on not having any
sidebars or other content to the inline-end (otherwise the [mirror] rule
would be incorrect), explicitly position it against the
.browserContainer.

Bug 1779202 - Disable use of CGLayer-backed cairo quartz surfaces to work around scaling bug affecting XObject images in pdf.js output. r=dholbert

This avoids the apparent Core Graphics bug whereby the PDF output it generates will mis-render
when subsequently processed again by Core Graphics (although it renders OK in Adobe products).
Unfortunately, this will regress bug 1772225, so that pdf.js documents will be rasterized when
printed or in Save to PDF output on macOS.

(Setting the pref gfx.cairo_quartz_cg_layer.enabled to true will restore "good" (vector-based)
output, but embedded XObject bitmap images may be mis-scaled.)

As noted in DelazifyTask::Create(), the VM should continue working if
delazification fails, so we can ignore them.

The new test was triggering the assertion at

https://searchfox.org/mozilla-central/source/js/src/frontend/BytecodeCompiler.cpp#71

because some errors were being reported to ErrorContext and ignored, while some were
reported to JSContext and not ignored.  Now, errors during delazification are
reported to ErrorContext if they are reported at all.

If this assertion fails (due to gigantic sizes), we'll essentially just produce
layout that's broken to some extent. In the included testcases, the text just
renders as if `text-align-last: justify` were not set; and if there are
multiple descendant spans, then any beyond the first may not be visible.

Due to https://gitlab.gnome.org/GNOME/gtk/-/issues/5089 don't use wl_subsurface popup for menus/tooltips, just for panels which can be resized.

Differential Revision: https://phabricator.services.mozilla.com/D156540

When we open a popup window (tooltip for instance) on top of GDK_WINDOW_TYPE_HINT_UTILITY popup, Mutter compositor sends bogus
leave/enter events to the GDK_WINDOW_TYPE_HINT_UTILITY popup (https://gitlab.gnome.org/GNOME/gtk/-/issues/5089).

That leads to immediate tooltip close. As a workaround ignore these
bogus events.

We need to check two affected window types:

- toplevel window with at least two child popups where the first one is
  GDK_WINDOW_TYPE_HINT_UTILITY.
- popup GDK_WINDOW_TYPE_HINT_UTILITY with a child popup.

We ignore two bogus leave/enter sequences which are fired by mutter together:

 1. Leave (popup) -> Enter (toplevel)
 2. Leave (toplevel) -> Enter (popup)
