[Bug] PermissionsViewer doesn't close user popout when opening full permissions view

[Leah96xxx]

Which plugin/theme is this about?
PermissionsViewer

Describe the Bug
When clicking the 3 dots next to the "Permissions" section in a user popout, the user popout will remain open. You can then click the 3 dots a seemingly unlimited number of times to open multiple instances of the permissions view on top of each other. Of course, it you clink anywhere outside the popout it will close, but I'd expect it to either close itself or move to the background with the rest of the main UI to prevent further interaction while the permission viewer is open.

To Reproduce

1. Open any user's popout and click the 3 dots next to "Permissions"
2. Notice that the Permission viewer opens, but also the user popout stays open, and click the 3 dots again
3. Repeat as many times as you like for infinite permission viewers

Expected Behavior
For the user popout to either close itself or move to the background with the rest of the main UI to prevent further interaction while the permission viewer is open.
