+
+ Reviewed by Simon Fraser.
+
+ The shadow tree for media controls is scheduling style recalc. The general silliness of
+ HTMLPlugInImageElement::willRecalcStyle/willDetachRenderers is turning those into render
+ tree reconstructions causing flicker.
+
+ * html/HTMLPlugInImageElement.cpp:
+ (WebCore::HTMLPlugInImageElement::willRecalcStyle):
+
+ Don't do the forced renderer reconstruction if there is no style change for the element
+ or its ancestors. This way recalcs scheduled by the shadow tree don't trigger the widget
+ update code path.
