Hi WebKit, I hope you can help me with ideas on how to create a test for the bug where layout update does not happen (https://bugs.webkit.org/show_bug.cgi?id=24453 ).
The bug is caused by timeout code using Document::updateRendering() instead of Document::updateDocumentsRendering() so it can miss the actually changed document. However, many things trigger layout so any attempt to dump the render tree, use layoutTestController::display() etc do not 'catch' the buggy behavior since all of them trigger layout. I have a test that is based on extending layoutTestController to expose FrameView::needsLayout() but it does not feel right to me to expose internals. Perhaps anybody had a need to write a test for missing layout update before.. I would appreciate all possible ideas about it! Thanks, Dmitry
