file picker is not working with live preview

[abose]

Describe the bug

Hi I tried to use file picker to save to local file but it is not working with live preview due to following error:

Error saving file: DOMException: Failed to execute 'showSaveFilePicker' on 'Window': Cross origin sub frames aren't allowed to show a file picker.

Additional context

This cannot be fixed with our current iframe based impl. But in the future, when we migrate to tauri 2, if we can embed web tauri webviews directly as the live preview surface, this is doable.
