Signal window not 'manageable' after restoring from the 'tray' window

[hipnoizz]

Describe the bug
After running Signal (https://signal.org/), closing it and reopening PaperWM is not able to manage the Signal window - it can't be really moved or resized etc.

To Reproduce
Steps to reproduce the behavior:

1. Install Signal.
2. Run it (signal-desktop).
3. File->Preferences, then General->System, and check Minimize to system tray.
4. Close the window, and run Signal again (I think this is needed to the apply the above setting). You should see the Signal icon in the tray now.
5. Close the Signal window.
6. Click on the tray icon and click 'Show'.

Now Signal window looks our of order - see the image below (the red rectangle is just the obscured contact list, ignore it please). With many windows it won't be even visible - in the windows overview it will be placed in some weird location between workspaces. It cannot be really moved - after clicking on the title bar and moving the mouse it will disappear until the button is released. It won't react to PaperWM shortcuts (move the window left or right etc.).

System information:

Distribution: Ubuntu 24.04.4 LTS (Noble Numbat)

Display server: Wayland
PaperWM version: 49.0.1

Additional context

Alt+F2, then lg and collecting a bit of windows info via JS shows (sorry, I don't know how to copy from the Looking Glass console):

So the height/width of the Signal window is 0.

I added the following winprop rule to PaperWM - that forces the width = 600 px and seems to work around the issue:

I didn't dig deeper - I think that Signal is an Electron app, maybe it resizes the window in some weird way after restoring from the tray.

Note that the winprop rule does not seem to work reliably - it seems to work better when the forced width is smaller, but it does not work always for e.g. 300px either. Or maybe even more strangely - it works first time when the rule is created/updated, then after the Signal window is closed and re-opened it is usually broken, and then changing the forced width again will make it work for the next time. At the very beginning when I created the winprops rule it seemed to work each time, but then it seem to get worse.

I have run into this before. IIRC, it is an electron issue.

Make sure signal is up to date. Then check if signal is an xwayland app or wayland app. Then switching to the other windowing system and see if it helps.

FWIW, the issue on my machines went away after a few updates
