Title: Fixes #12139, make sure absolutely positioned elements have HTML as offsetParent

This issue was already fixed in this commit: https://github.com/jquery/jquery/commit/b398a68333d5eb9859fabb1ceabe84a1a753760a , however, I wanted to add a unit test to prevent a regression as described in the ticket.
