Reland "Reland "[PE] Fix background-image on ::first-line""

This reverts commit 3edb3f1bbe315083871126bcbe4d422556b0d69f.

Fix by moving UpdateFirstLineImageObservers() from
CachedFirstLineStyle() into GetCachedPseudoStyle() to ensure
we update image observers for the correct object.

Reland "Reland "Reland "[PE] Fix background-image on ::first-line"""

This reverts commit 36dab48068086f08eacf7f283293d6ce49493440.

Reason for revert: Reverting broke the compilation. A broken test is better than a non-compiling tree.
