Programming exercises: Inline feedback sticks to top of online editor

[b-fein]

Describe the bug

Sometimes inline feedbacks get stuck to the top of the online editor.

To Reproduce

In a programming exercise with manual assessment:

1. As tutor/instructor assess a submission and add various inline feedbacks.
2. When switching back to files where you added annotations before or when scrolling around within a file, sometimes some of the inline feedback items get stuck to the top of the editor as shown in the screenshot.

It might take a few minutes of adding feedbacks, changing files, and scrolling to reproduce the bug.

Expected behavior

The feedbacks are not sticky but are shown at the correct location.

Screenshots

Two inline feedbacks overlapping and stuck to the top of the editor box even when scrolling:

Issue existing again in 6.6.0, looks like #7099 did not fix this.

Can be reproduced:

1. Have an inline comment in line 1 of file A.
2. Switch to file B and scroll down.
3. Switch back to file A.

Tested for an already saved assessment.

#7396 implemented a fix that is working for the common case of file-switching.
