Automatic update from web-platform-tests Fix the lack of damage tracking for root layer position changes in BGPT. Previous to this CL, if the position of a layer changed, and that layer was the root layer targeting a render surface, the old location of the surface was not damaged in the *parent* render surface. With BGPT disabled, this was masked by transform_changed being set at [1], which triggered the conditional at [2] and caused the old location to be damaged. With BGPT enabled, transform_changed is never set. The new logic here detects LayerPropertyChangedNotFromPropertyTrees() for a root layer, and triggers the conditional at [2].
