"Loading Patchwork (100%)" forever if Patchwork sidebar is floating

[wjt]

This seems unlikely but I can reproduce it reliably.

• Dell XPS 13 9343
• Two displays
• Endless OS / GNOME 43
• Wayland desktop session
• Godot running as X11 client (the default)

Steps to reproduce:

1. Open a Patchwork project (and join/create if not already connected)
2. Make the Patchwork dock floating to work around Reduce sidebar width #72:
3. Without closing the floating dock, Project -> Reload Current Project (or restart the editor on the same project in some other way of your choice)

Expected results:

1. Godot reopens
2. Patchwork dock floats again
3. "Loading Patchwork" popover eventually disappears

Actual result:

• 1 & 2 occur
• 3 does not: "Loading Patchwork" remains at 100% forever. (I tried to be patient and waited about 20 minutes while having another conversation.) But during this time the rest of the editor has initialised, including the Patchwork sidebar, and I can see my testing partner's changes flowing in.
• Only after giving up on the testing session (and reproducing this several times) did I try closing the floating Patchwork window, which re-docks it into the main window. Doing so immediately dismisses the Loading Patchwork popover.
• Having redocked the sidebar, reloading the project is relatively quick, just a few seconds of "Loading Patchwork".
