TotalSpace automatically switches spaces

Here’s a pattern I’ve observed:

Context

  • There’s a problematic application. Determining which one is difficult; however, let’s say it’s Calendar.
  • Desktop 11 has Messages; Desktop 12 has Calendar
  1. Focus Messages
  2. Focus Calendar (via hotkey, Cmd + Space search -> select application – however)
  3. Focus Messages again (either directly, or with the shortcut setup for Switch to previous space
  4. Desktop 11 (with Messages) briefly appears; it then quickly reverts to Desktop 12 with Calendar
  5. At this point, if Calendar is explicitly clicked and then Messages is focused OR Desktop 11 is switch to, the issue is gone

I’ve been struggling with this / trying to replicate it / trying to fix it ever since Catalina came out. I usually just logout/login (or restart); these steps are the first pattern I’ve been able to properly observe.
