Attachment: Video of the reporter reproducing the bug

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

1. Navigate to your favorite image, hosted on the internet (your Bugzilla profile pic, perhaps)
2. Copy the image with right click, "Copy Image"
3. Paste the image onto any desktop app that supports image uploading. I personally always have Discord open.

Actual results:

The image is pasted twice, and, in the instance of Discord: triggers two file upload prompts.

Expected results:

The image is pasted once.

We've reproduced this bug on the Element Desktop app as well.

This sounds similar to bug 1716016. Most likely discord needs to change their code.

This bug is only reproducible in apps not running Electron 14. I believe this to be an Electron bug and will work on finding Electron's commit that fixes this to close this and bug 1716016.

Yeah, seems to be an Electron bug, see https://github.com/signalapp/Signal-Desktop/issues/5510#issuecomment-917093938.

It is a Electron bug, so close as INVALID.
