Revert buggy pr (#28554)

Earlier, I merged #24723

Before merging it, I made a change that was incorrect and fast followed
with a fix: #28548

Following that fix, @bennetbo discovered that the modals where no longer
highlighting correctly, particularly the outline modal.

So I'm going to revert it all.

Release Notes:
