I'm unable to reproduce on Fedora 34 / gtk3-3.24.30 / mutter-40.5-2.fc34.x86_64.
Can you create a screencast of it?
Is there any change if the popup is opened repeatedly?

Can you please attach log of

MOZ_LOG="WidgetPopup:5"

please?

The vertical height of the popup is fixed to the initial height of the overflow menu. If there is only one item in the menu then the height is very small and clips most extension panels.

Thanks for the sceencast. I see flickering of the popup when content is switched but I don't see the resize failure.
Which Gtk3 version do you run?

Correction - seems to be fixed by some of the latest patches, works for me with nightly 95.0a1 (2021-10-12).
