Summary [CSS Regions] Assert when entering fullscreen from a video element

Created attachment 176114 [details] test case Adding a video element to a region flow thread and making it fullscreen will throw a bunch of asserts. I've seen https://bugs.webkit.org/show_bug.cgi?id=102957 reproduce, but patching that will get into different other issues. I've been using the controls to make the video full screen.

I've seen https://bugs.webkit.org/show_bug.cgi?id=102957 reproduce, but patching that will get into different other issues. I've been using the controls to make the video full screen. Are you using Chromium? On the Mac port the crash happens before going fullscreen, when moving the cursor over the video element.

Works for me on today's nightly (r151543)

Nightlies are release builds, that's why you don't get the asserts. Reopening as video is one of the important things that must work in Regions.
