Online-editor overrides (student) submissions with other file content

[NadeoWolf]

Describe the bug

Sometimes submitted files/classes get overridden by the content of other files/classes.

To Reproduce

This does not always work:

1. Make some changes to one of the files
   • maybe position matters, so in my case the first file
2. Press Submit
   • in our case we use Jenkins to build
3. While building, switch between files/classes
4. Wait for the build
5. (Pressed by accident, maybe optional) Press Ctrl+S and close the save window again
6. Switch in the online editor between both classes

Expected behavior

Keep the original file content.

Hi, we are currently facing the same problem with our setup. The files were permanently overwritten and could not be brought back by clicking on the refresh button or reloading the page.

Reproduced in 8.3.4
Checked with a pure student account "solving the exercise" .

Edit:
This bug is not directly in the commits. First, it is only in the editor cache, but for all users. So when we checked with another user, it showed the overridden file. Only after submitting again will it appear in the git commits.
