From github: https://github.com/mozilla-mobile/fenix/issues/17599.
Can I pleae report that ever since release 85.1.0 all 'slideshow type' news articles they call "Galerie" of the German news portal web.de became essentially unusable.
These pages are one of several templates the news portal uses repeatedly, and can be discovered by looking for the white text on gray background "Galerie" label of certain articles on https://web.de, in particular under https://web.de/magazine. They consist of a slideshow type series of pictures which can be swiped consecutively from right to left, while for each picture an accompanying text can be pulled up or down from the bottom to display as an overlay or collapse. All these functions worked flawlessly up to and including release 84.1.4.
85.1.0 introduces the issue that the actual content area of the page becomes blank (white) at some point, leaving only the slide counter and the 'X' exit control visible. At this point tapping the 'X' seems the only option left, you cannot advance the article any further. The issue is best reproduced if you perform a pinch zoom in any picture area of such a Galerie type web page. But the appearance of the issue is not limited to pinch zooming, it often appears, less regularly reproducible, when swiping through such a web page, or showing/hiding the overlay text.
I am using Firefox 85.1.0, with Firefox's 'Desktop site' option being off, on several devices, e.g. the Samsung Galaxy Xcover 4 and 4s.
A deep link to an example page is https://web.de/magazine/politik/us-politik/joe-bidens-wahl-symbolisiert-neustart-usa-oval-office-35463756, but this issue applies to all articles found on https://web.de/magazine/ which are labeled with the white text on gray background expression "Galerie". On each you have to the tap 'Bildergalerie starten' to enter the article slideshow.
I attach 2 screenshots of how such a webpage appears before and when the issue appears.
Change performed by the Move to Bugzilla add-on.

Can reproduce this realiably on latest GVE by accessing https://www.gmx.net/magazine/gesundheit/corona-zahlen-inzidenz-r-wert-neuinfektionen-zahlen-falsch-verstehen-35572664 and zooming in on the image.
Recording from a Pixel 3 with Android 11 - https://drive.google.com/file/d/1AZny1Cw8urOqx-uFLZAie1Hzrp3dTB8l/view?usp=sharing
Doesn't seem to happen on other browsers.

Seeing the same behavior on desktop (release 86), moving the ticket to Core.

Opening devtools also reproduces the problem.

I think this might be layout. The figure element that contains the image becomes 0 height when the problem happens and the html element starts overflowing.

Doesn't seem to be a (recent) regression to me. I can reproduce at least as far back as 2017, before that macos builds don't work for a few years and then before that the site doesn't work for some reason.

Works fine for me in a Linux desktop build, fwiw.

The original reporter left a comment about this not being an issue anymore in Fenix - https://github.com/mozilla-mobile/fenix/issues/17599#issuecomment-809108301 and I also cannot reproduce anymore when zooming the fullscreen image from comment #1 even in Firefox Desktop Release so I think a recent change in that particular website fixed that particular issue.
Wasn't able to reproduce this issue with opening dev-tools in Firefox Desktop so I cannot confirm whether there is work needed for this.
