Only one tab can be moved to another group without restarting Orion

Steps to reproduce:

Move more than one tab to another group. Switch to said group. See only one of the moved tabs. Restart Orion to see all moved tabs.

If you try to move tabs to another group again without a restart, it seems nothing happens. Restart fixes this again (luckily). So, you can only ever see one moved tab, you need to restart to see all the moved tabs after the first one.

Have tried Compatibility mode, made no difference.
