Comment on attachment 42205 [details] Fix assertion falure in RenderObjectChildList::updateBeforeAfterContent(). For an assertion-only change, I don't think a test case is required. The test says "passes if it does not crash", but that's misleading. This only ever asserted, it wouldn't crash in a non-debug build. r=me
