Someone tells Neko there's a problem with the passthrogh.

I'm unable to understand the passthrough implementation at apps\stage-tamagotchi\src\pages\index.vue. Chat & settings icons aren't displayed when Alt+Shift+I + hovering, idk why

I discovered that as well, the impl here might have issues, feel free to raise another issue for this. Try toggle it twice, it should appear.

The similar bug appeared on passthrough feature, which is fixed by https://github.com/moeru-ai/airi/pull/449/files#diff-3f7ee1faa56af6a84cdfdd4af79955bbe9defb238c85072803782db29467e033L241. Togglling twice doesn't work.

@typed-sigterm what I can see its inverted, maybe you can leave it first,

Anyway shortcut is always buggy to me, its prioritize to call to top windows first
