Callum Law 3aff3327c4 LibWeb: Invalidate layout on opacity change to/from zero ...

As of 7dc8062 paintables compute and cache their visibility (which
depends on opacity) at construction - this cached value can fall out of
sync with reality if if the opacity changes to/from zero within the
lifetime of that paintable.

This commit invalidates layout when an opacity changes to/from zero so
that we reconstruct paintables with the correct visibility.
