Tauri Print Repro

Minimal reproduction for macOS iframe print behaviour in Tauri.

It has exactly two buttons:

• Print window: calls window.print()
• Print iframe: calls iframe.contentWindow.print() on the iframe to its right

In Tauri on macOS, Print window works when core:webview:allow-print is present, but Print iframe never works. Both buttons work in Safari and other browsers.

Reproduction steps

1. Run:

   npm install
   npm run dev

2. Open Safari
3. Press both buttons and see that they both spawn print dialogs
4. Kill the server, then run:

   npm run tauri:dev

5. Press both buttons and see that only the Print window button works
