Programming exercises, Assessment: Unnecessary empty space below tutor comments

[b-fein]

Describe the bug

There is quite a bit of empty space below inline code editor comments. The actual amount of space seems to differ based on some browser/font settings per user.

To Reproduce

1. Assess a programming exercise submission and add inline comments.

Expected behavior

There is less empty space below inline comments.

Screenshots

The actual amount of empty lines seems to be minimum one, but up to three depending on the system font settings. The space without line number could be reduced/removed.

Which version of Artemis are you seeing the problem on?

6.1.1

What browsers are you seeing the problem on?

• This includes the default margin-bottom: 1em of the .alert class.
• Development: Add client support for programming exercise feedback suggestions #7099 will probably fix this:

• There also is (still) an issue where when you have the instructions / the file browser open initially and then close it, the height of the feedback card is changed, but the reserved space within the editor is not.
