Window focus switching buggy due to `@!0,!0;BDHF` window

[hoodmane]

Issue/Bug Description

Super + focus sometimes doesn't correctly move focus. Instead the focus lands on a window called @!<###>,!<###>;BDHF. It seems to happen most often when focus should change monitors. I fixed it with the following patch:

diff --git a/src/focus.ts b/src/focus.ts
index 91ede48..0433f1a 100644
--- a/src/focus.ts
+++ b/src/focus.ts
@@ -51,7 +51,7 @@ function select(
     focused: ShellWindow,
     window_list: Array<ShellWindow>
 ): ShellWindow | null {
-    const array = windows(focused, window_list);
+    const array = windows(focused, window_list).filter(win => !win.meta.get_title()?.endsWith(";BDHF"));
     return array.length > 0 ? array[0] : null;
 }

Steps to reproduce (if you know)

Not sure.

Expected behavior:

Select the next window over.

Big thanks for the sharing the temporary fix! I experienced the same bug and the fix worked. Using Ubuntu 23.10 Mantic Minotaur with Gnome Shell 45.2 and Pop Shell commit 9a30c5b in master-mantic branch.
