Caused by bug 1645817 maybe?

Confirmed it is caused by bug bug 1645817. This is basically 100% reproducible on my ubuntu 19.10 machine with this command line:

GTK_OVERLAY_SCROLLING=0 ./mach mochitest accessible/tests/browser/bounds/browser_test_resolution.js --verify

I believe GTK_OVERLAY_SCROLLING is needed to make it like the machines in automation which I'm fairly certain have overlay scrollbars disabled, but probably via a method other than this environment variable.

Regressed by: 1645817

The reason for the crash is that overlay scrollbars are in a different position in the display list and there is a delay between LookAndFeel::GetInt(LookAndFeel::IntID::UseOverlayScrollbars) (in ScrollFrameHelper::AppendScrollPartsTo) returning the updated value and the prescontext doing the necessary processing to handle a ThemeChanged notification that comes from PresShell::Observe getting the topic "look-and-feel-changed".

accessible/tests/browser/bounds/browser_test_resolution.js started flipping on the pref ui.useOverlayScrollbars in order to run it's test properly.

Changing the pref ui.useOverlayScrollbars is first handled in the look and feel code. A "look-and-feel-changed" notification is sent out. PresShell::Observe receives this and calls nsPresContext::ThemeChanged. This queues a runnable. This will eventually reflow all scrollframes via the call MediaFeatureValuesChangedAllDocuments in nsPresContext::ThemeChangedInternal. But before that can happen we can paint, and |LookAndFeel::GetInt(LookAndFeel::IntID::UseOverlayScrollbars)| will return the new value. Which means ScrollFrameHelper::AppendScrollPartsTo will place the scrollbars at their new position in the display list and nothing has marked the scrollbars as modified so we fail to merge.

Do a full display list rebuild if scrollbars change to or from being overlay scrollbars. r=miko
