Steps to reproduce:
Create a WebApp for WhatsApp (that's sounds fun) or create a webapp for docs, try to download something, like exporting to pdf or downloading a document in WhatsApp, it completes successfully but the file is gone somewhere we cannot find.
The file should be in the downloads folder or a save file popup should be there
