Expected Behavior

1. Click on a link that will fire the will-download event.
2. You should see a dialog pop up as to where to save the file. Select a file that already exists.
3. The user is prompted to replace the file. Select Replace.
4. The file is successfully replaced on the drive.

Actual Behavior

Instead of the file being replaced, the download state changed to interrupted after the file transfer is complete. The file is not replaced and remains in its original state.

Testcase Gist URL

No response

Additional Information

This only reproduces on MAS builds. I've been generating them using electron-builder. I can try and come up with a Gist if that would be helpful.

I added the required entitlement com.apple.security.files.user-selected.read-write which allows me to read and write files, but apparently replacing them does not work. HOWEVER, if you add the specific entitlements for special folders in the users (eg. com.apple.security.files.downloads.read-write) it will allow you to replace files in the specified folder and will not cause the download to be interrupted.

I'm guessing something's a little wonky with the permissions for replacing files with the user-selected entitlement.
