<!-- 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. -->
