Steps to reproduce:

Go to Below "Lieblingsprodukte" there should be an image gallery consting of 5 images.

Actual results:

The images are not visible. Only on mouseover the images are flipped and replaced by other images.

Expected results:

Just as it is in Fx 43 or Fx 44: The images should be visible. It works in the stable Fx but not on current Developer Edition or Nightly. I just tried.
[Tracking Requested - why for this release]:
Component: Untriaged → Layout
Ever confirmed: true
Keywords: regression
Product: Firefox → Core
Tracking since this is a regression
The above linked website just uses a common wordpress theme. The bug is also visible on these themes:
* (under "Products on Sale")
* (under "Featured Products")

Interestingly, when you switch to the last link from another tab, then the images a visible for a fraction of a second, then it the images become invisible again.
I wonder why nobody is assigned, so nobody taking care of this regression?

Virtue and Pinnacle themes are among the most popular wordpress themes with about 100K installations, so this will break a lot of sites.
Attached file reduced testcase
AR: nothing displayed
ER: should display "foo"

OK on m-c, adds a test, helps with preserve-3d regressions.
Please uplift to aurora.
