📝 Provide detailed reproduction steps (if any)

1. Upload an image.
2. Refresh the page during uploading.

✔️ Expected result

After the refresh it should be indicated that the upload it was not successful.

For the built in GitHub, after the refresh session resume feature just shows shows the image as a link to the issue, and user can add comment.

What is the actual result of the above steps?

The image is "uploading" infinitely, and the comment cannot be added until the link is deleted.

Hi,

It may sound very much weird but I was working intensively on a single file for last 8 hours. Making some notes actually about tech. I accidently pressed some button. It did not asked me anything like discard changes or something. But I later realized that what I did. I tried to press back button and I can see that the editor is empty. Its 5:22 AM Ist and I was working since last evening yesterday. Is it anything I try possibly to get my data back? Thanks in advance
