I wonder if this is even the right way to think about it or approach it. If I was to build a in-browser file-editor I would approach these features like this:

1. Open File
2. Save File
3. Download File

1- Opening a file happens the usual way with <input type="file"> and the FileReader API
2- The file is saved to IndexDB
3- A prompt is given for download using the method you're describing above.

In case #2 you would be able to listen for completion and have confidence that the file saved properly

In case #3 you don't care as it's not being used in by application (like auto-save). Treat this last case like "Export" instead of "Save"
