    <thetext>The patch in PR https://github.com/WebKit/WebKit/pull/43626 fixing bug 290993 is making the WPT test `scroll-animations/css/animation-range-visual-test.html` hit `ASSERT(repaintContainer-&gt;isComposited())` under `RenderObject::repaintUsingContainer()`. This test is being skipped to avoid hitting this crash on the bot, but we need to fix this.</thetext>
