+ <!-- Test that a fixed background layer inside an inactive layer tree
+ is clipped correctly. Here, the inactive layer tree is created by
+ the SVGEffects display item built for the clip-path on the outer div.
+ The bug only reproduces in XUL because fixed backgrounds are only
+ layerized if their animated geometry root is the root frame, but
+ in HTML there's always an enclosing HTML scroll frame. -->
