This is a regression from bug 1582530 (more spefically, the Fix remaining cases that were relying on blockification patch)

See attached.

This doesn't really make sense to me; it doesn't look like that change touched the arrow in any way so I don't see how it'd affect this...

Anyway, :ntim/:dao/:dholbert, thoughts?

This was likely a regression from the other patch in that push, which flipped a pref to make it so some XUL elements that were implicitly getting forced to display:block will no longer have their display changed like that (so now they remain display:-moz-box).

If I flip layout.css.xul-box-display-values.survive-blockification.enabled = false and then enter customize mode, then I get EXPECTED RESULTS. (No need to restart Firefox even).

So this was definitely a regression from that pref-flip, and we likely just need to add an explicit display:block for some element here.

looks like the rule for...

#customization-panelWrapper > .panel-arrowbox {

...needs display:block, because that element's parent #customization-panelWrapper is display:flex, and flex containers blockify their children. (And until now, that has meant that it forced its child to display:block, but now it leaves it at display:-moz-box instead, which has a subtly different layout in this case, hence this bug report.)
