Jelle Raaijmakers f5bb5d0797 LibWeb: Don't tear down an active effect saveLayer during culling check 
Before applying an effect context (filter, opacity, blend-mode), the
display list player runs a culling check by tentatively switching to the
effect's parent first. When the effect was already on the stack (i.e.
the current context was a descendant of the target) that walk restored
the saveLayer prematurely. The filter was then applied to a partial
batch of commands, and subsequent commands opened a fresh saveLayer for
a second, independent application, producing visibly wrong compositing.

Fold the culling check into switch_to_context: while walking down to
apply contexts, check the bounding rect right before each EffectsData
node and abort if the command is fully clipped. Walks that only go up
never traverse an EffectsData node, so an already-applied effect is
never torn down.

This regressed in cd0705334b.
