Steps to reproduce:

According Arai from IRC, mozregression tells it's a regression from bug 1143570.
He confirmed that backing out fixes this.

No link is clickable.

Expected results:

Links should work.

This seems to be a minimum set.
So, clickable item inside floating box, another box with "position: absolute" style, followed by another (maybe inline) node.
(maybe the bottom-most line of the last element matter?)

If I hover mouse on the text "B", the dropdown menu become clickable.

In the page, most contents are inside floating boxes, and there are several "position: absolute" boxes, followed by an image element with width="2" and height="2", which is placed around top-right corner of the page.
I can confirm that on a daily compiled just now the following page
does not work. The links (Fahrzeugsuche, Werkstattsuche, Verkaufen, etc. ) in the menu don't respond and all the other links on the page don't work either.
Backing out fixes this.
Sorry, this was hard to believe, so I had to try it myself ;-)
roc, are you OK with a backout of plus a patch that adds a test for it?

sorry had to back this out for test failures like

I fixed the test.  The key was changing the 10px padding to 20px.

Adding a tracking flag for FF41. I tried to open the STR link on FF40.0a2 2015-06-03 and do not see the problem, therefore setting FF40 status as "unaffected".
(sorry to interfere, why wasn't this marked fixed?)
Flags: needinfo?(cbook)
Confirmed, its fixed.

Sorry to interfere: Why does this have an Aurora (Mozilla40) request? The original patch was never landed on Mozilla40, so it would be hard to back it out ;-)
