LibWeb: Don't early return when masking area of StackingContext is empty

Browse source 
An early return was occurring between the emission of
PushStackingContext and PopStackingContext, resulting in a
PushStackingContext without a corresponding PopStackingContext in the
display list, which caused broken painting.

Fixes black screen on Discord login page.
