Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.69.0
• OS Version: Linux wayland backend

Steps to Reproduce:

• Under any wayland desktop
• Force wayland backend for vscode

$ cat ~/.config/code-flags.conf 
--enable-features=UseOzonePlatform
--ozone-platform=wayland

• Any top level window under wayland is identified by app_id which used to be equal to "code" and now it is an empty string.

This bug is probably caused by switching to electron 18, electron/electron#33578
app_id is the only real way to differentiate windows under wayland if you are using a tiling window manager and want to pin some applications to some workspaces.
