This is a bug introduced in March 17th, 2023 firefox nightly.

If you have a webpage with a dropdown menu widget, when you click on it to list every available option, list is displayed in the top left corner instead of below widget.

I added a picture to show this weird bug.

I'm using Archlinux + Gnome.

Using mozregression-gui, I found that the last working commit was 526b311a and first broken one was c15f0fb1.

A regression related to fix for bug 1809084 ?!

Yeah it seems Wayland specific somehow.

Attachment: Bug 1823020 - Set mUntransformedAnchorRect for rect-anchored popups. r=stransky,#layout

I missed setting mUntransformedAnchorRect in one case, causing Wayland
popups to be wrongly positioned.

I'm going to land it since it's effectively a one-liner for a non-tested (on trunk) configuration, and it's a rather annoying bug. But Martin and/or David, if you can take a look it'd be appreciated. :)

It is still broken for Other Bookmarks dropdown list and for printer selection when you want to print a web page.

Well the patch hasn't made it to central yet so latest nightly still has the bug.
