Since nightly and release are affected, beta will likely be affected too.

I can reproduce the issue on Nightly135.0a1 Windows11 if browser window is the minimum width.
Regression window:

:emilio, since you are the author of the regressor, bug 1923201, could you take a look? Also, could you set the severity field?

This is unlikely to be a layout bug, the site works correctly with a Chrome UA.

Ah, the site has:

@media (max-width: 959px) {
  html.firefox .row div[class*=col-lg-].pos-bottom,
  html.firefox .row div[class*=col-lg-].pos-middle {
    height: inherit !important;
  }
}

That would do.

The bug is marked as tracked for firefox133 (release), tracked for firefox134 (beta) and tracked for firefox135 (nightly). However, the bug still isn't assigned.

:twisniewski, could you please find an assignee for this tracked bug? Given that it is a regression and we know the cause, we could also simply backout the regressor. If you disagree with the tracking decision, please talk with the release managers.

Are we planning to ship this intervention in 134?

I'm not against uplifting it if we feel strongly enough to do so, but I was not planning to do so.
