CrashTracer: com.apple.WebKit.WebContent at WebCore: WebCore::Document::updateStyleIfNeeded
https://bugs.webkit.org/show_bug.cgi?id=182299
<rdar://problem/36853088>
Reviewed by Simon Fraser.
Source/WebCore:
Mostly speculative fix for the case where a scrollTo moves an
animated SVG image into view, causing its animation to restart during
a paint operation. This was causing a release ASSERT, so we now defer
the resumption of the animation into a timer.
Test: svg/animated-svgImage-scroll.html
* rendering/RenderElement.cpp:
(WebCore::RenderElement::repaintForPausedImageAnimationsIfNeeded): Enqueue the
animation if it is an SVGImage.
* svg/graphics/SVGImage.cpp: Add a timer to enqueue animation starts.
(WebCore::SVGImage::SVGImage):
(WebCore::SVGImage::startAnimationTimerFired):
(WebCore::SVGImage::enqueueStartAnimation):
(WebCore::SVGImage::stopAnimation):
* svg/graphics/SVGImage.h:
LayoutTests:
* svg/animated-svgImage-scroll-expected.txt: Added.
* svg/animated-svgImage-scroll.html: Added.
