1. Open a Dialog

The dialog should prevent access to the main window while open

Will be fixed when (and if) PolyMeilex/rfd#14 is merged and published.

Out of curiosity, there is also a bug where the dialog window spawns below all other windows most of the time. Would this be fixed as well with this change?

I hope it will, since we'll set the tauri window as parent of the dialog, I think Windows will handle that.
