New issue by baal-zebub on void-packages repository

https://github.com/void-linux/void-packages/issues/33758

Description:
### System

* xuname:  
  Void 5.13.19_1 x86_64 AuthenticAMD uptodate rrrmFFFFFF
* package:  
  sway-1.6.1_1

After updating some packages (xbps logs below) I'm no longer able to start sway neither from lightdm (which worked before) nor gdm. Running it from tty works, but some things are broken - i.e. waybar won't start and Firefox won't restore sessions even though the appropriate setting is enabled.

Here are the xbps logs from the last `xbps-install -Su`:
