[bug] hanging when showing window in windows

[Sheap]

Describe the bug

When calling window.show() the app becomes non responsive. I have an example showing the issue here: https://github.com/Sheap/tauri-window-test

This only occurs on my windows machine. I have tested it on both linux and mac, and have no issues.

Curiously, in my application I have a splash screen set up as per the documentation, which includes calling .show() on the main window, which works without issue on all OSs, suggesting the issue is specific to secondary windows.

Reproduction

1. clone https://github.com/Sheap/tauri-window-test on windows
2. pnpm tauri dev
3. press the "Toggle Popout" button
4. The popout window will appear, but then the app will freeze (both windows)
5. console will show the print statements from before the show call, and none after it.

Expected behavior

The app to remain responsive
