Persistent UI that operates like a window messes up all layouts

[camdub]

Describe the bug

I recently downloaded https://www.flowvoice.ai/ to try out. It adds this persistent pill UI to the bottom of the main display that toggles on/off to display when Flow is capturing audio (see image below of pill in the "off" state).

When launching Aerospace, the layouts did not work as expected. I tracked it down to the fact that it treats Flow as an open window, but there is no actual window to move. I tried moving Flow to its own workspace but that caused the floating pill to blink and move wildly. Quitting the Flow app entirely and restarting Aerospace fixed the issue and I was able to operate it normally.

Related issues you could find

• Closed windows are not removed from the tree on macOS 15 Sequoia #471
• Allow excluding windows from AeroSpace #552 - This was the first thing I tried to look for to just have AeroSpace ignore this app

Notes

• using the default config
• AeroSpace v0.15.2-Beta
• macOS Sequoia 15.1.1
• the debug-windows command does not print any output from the Flow "window"
