[bug] Tray window blur event not triggered after second show() call

[i-CNNN]

Describe the bug

I created a custom tray window in Tauri. When I first call window.show() on the tray window, triggering a blur event (e.g., by clicking outside the window) correctly hides the window. However, after calling window.show() again to redisplay the tray window, the blur event no longer fires when the window loses focus. This prevents the window from being hidden again unless I manually click on the tray window first to "reactivate" it.

Environment:

• Tauri Version: [e.g., 2.5.1]
• OS: [e.g., Windows 11]

Reproduction

1. Create a tray window with WindowBuilder (or similar).
2. Call window.show() for the first time.
3. Trigger a blur event (e.g., click outside the window). The window hides as expected.
4. Call window.show() again to redisplay the tray window.
5. Attempt to trigger a blur event (e.g., click outside the window again). The event is not fired, and the window remains visible.
6. Click directly on the tray window to "focus" it, then clicking outside will finally hide it.

Expected behavior

The blur event should consistently fire every time the tray window loses focus, regardless of how many times show() is called.

1. Please include the output of the tauri info command as required by the issue template, thanks.
2. Are you using tauri's unstable feature flag?

Trigger a blur event (e.g., click outside the window). The window hides as expected.

i assume you're listening to the blur event and hiding it manually? can you share the code for that as well?

I rebuilt a demo project and removed the "unstable" features, after which the tray window can now show and hide properly. Thank you.
