Xianzhu Wang 3f9e384a14 Bug 1638689 [wpt PR 23662] - Fix composited outline layer order with overflow controls, a=testonly
Automatic update from web-platform-tests
Fix composited outline layer order with overflow controls

Previously when we updated the child layer list of a
CompositedLayerMapping, we reattached decoration_outline_layer_ in
GraphicsLayerTreeBuilder before calling CLM::SetSubLayers(),
and reattached overflow_controls_host_layer_ in CLM::SetSubLayers(),
causing wrong order of the two layers.

Now reattach both in CLM::SetSubLayers() (which will reattach more
layers when we adjust the tree hierarchy in later CLs).
