Subject: [PATCH] Bug 1115812 patch 14 - For rem unit change handling, repost
 min hint to root just like change hint.  r=heycam

This changes what was probably a silly design choice when I wrote the
code for 'rem'-basis handling; we shouldn't try continuing through the
rest of RestyleElement() here, but instead repost the hint to the
rebuild-all process.
