  What is mentioned on mozregression:
  DEBUG : Found commit message:
  Bug 1822131 - Allow XUL elements to shrink-by-default. r=dholbert
  Bug 1821920 and bug 1821871 are instances of an interesting behavior
  change from bug 1820534.
  The default flex-basis of old XUL was auto instead of max-content,
  because of this code:
  https://searchfox.org/mozilla-central/rev/af78418c4b5f2c8721d1a06486cf4cf0b33e1e8d/layout/generic/nsFlexContainerFrame.cpp#1327
  So stuff that used to wrap now no longer does, in an horizontal flex
  container, since xul.css prevents XUL elements from shrinking.
  Per the comment, a few tests relied on this, but I believe it should
  generally be safe to shrink the items. This only causes to shrink if
  they have an explicit width but no min-width (including min-width:
  auto).
  Some tests like test_mousescroll.xhtml hit this, because they have
  explicit sizes but min-width: auto ends up being 0 effectively, but I
  believe we should tweak those tests instead.

Based on comment #0, this bug contains a bisection range found by mozregression. However, the Regressed by field is still not filled.

:zombie and :emilio, since you are the authors of the changes in the range, if possible, could you fill the Regressed by field and investigate this regression?
