Dropbox 2022.12.05 tray icon menu unavailable in Ubuntu 23.04

Version appears to be: dropbox-lnx.x86_64-174.3.5762

Brand new Ubuntu 23.04 install.

Dropbox installs and starts syncing when opened from installed apps, but no menu is available when I right click the tray icon.

**Workaround:**

This does work after Gnome is restarted according to http://disq.us/p/2twv5ht, which is to lock the screen and unlock it.

There only appears to be one process `.dropbox-dist/dropbox-lnx.x86_64-174.3.5762/dropbox`, so I guess it gets some state nudged when I lock and unlock.

Start by reproducing the missing right-click tray menu on a brand-new Ubuntu 23.04 install with Dropbox version dropbox-lnx.x86_64-174.3.5762, and compare behavior before and after locking and unlocking the screen. The work is done when the tray icon menu is available without requiring a GNOME restart or screen lock/unlock.
