Bug: eqMac popover does not close when switching desktop spaces

[patrickrushton]

Describe the bug
Not sure if this qualifies as a bug or UX improvement, but if the eqMac popover has been opened on a different desktop space, then clicking the eqMac menu icon will fail to do anything

Steps to Reproduce
Steps to reproduce the behaviour (feel free to change the placeholder as you need):

1. Set up macOS with at least two desktop spaces
2. Click the eqMac menubar icon to open the popover
3. Switch to the other desktop space
4. Click the eqMac menubar icon again

Expected behaviour
Expected the popover to open on the new desktop space, but it doesn't do anything because the popover is actually still open on the other desktop space. Other menubar popovers don't have this issue because they are automatically closed when switching desktop space.

Update: a partial workaround is to temporarily change the behaviour to Dock, then right click the dock icon and choose Assign To All Desktops. Although then there is still some unusual behaviour with full-screen apps.
