Popup/tooltip UI element (not website) disappears upon activation of dropdown menu. The example is using the bitwarden extension, but I recall this affecting other popups as well (just cannot recall).

How reproducible:

Steps to Reproduce:
1. install bitwarden extension
2. activate popup using toolbar icon

popup disappears, but dropdown selector is drawn in correct location

Yes, it's fixed upstream in Firefox 69 (nightly).

Comment 2 Martin Stransky 2019-07-01 06:21:12 UTC
btw. can you try latest nightly? how-to is here:

Comment 3 Jan Vlug 2019-07-01 08:38:51 UTC
The drop drop down does not disappear any more in 69.0a1 (2019-06-30) (64-bit) nightly.
But it is sometimes incorrectly scaled. See attached screenshot.

Incorrectly scaled bookmark drop down menu

I also see some SELinux messages when using Firefox nightly. I do not know whether this is related.

Comment 5 Jan Vlug 2019-07-01 09:45:41 UTC
This is the SELinux issue: bug 1723308

Comment 6 Adam Chasen 2019-07-01 20:33:37 UTC
The issue was not present on nightlies. I was also unable to reproduce in non-wayland firefox. I believe the nightly is a non-wayland firefox as well.

Comment 7 Jan Vlug 2019-07-01 21:00:22 UTC
Start the nightly with the following command to run with Wayland backend:
MOZ_ENABLE_WAYLAND=1 ./firefox -Profilemanager

Comment 8 Adam Chasen 2019-07-01 21:08:07 UTC
confirmed fixed in window started with MOZ_ENABLE_WAYLAND=1 ./firefox -Profilemanager

Comment 9 Martin Stransky 2019-07-02 08:26:02 UTC
Great, Thanks. That will come in Firefox 68 or 69.
