Text exercise: Inaccurate inline feedback separation

[MaximilianAnzinger]

Describe the bug

When adding inline feedback for text exercises, the feedback for a line is incorrectly split when the line contains !=. (See attached screenshot)

To Reproduce

1. Go to Assesment for a submission that contains !=
2. Add inline feedback to the line.
3. You can either select the part before or after != (!= is split in two)

Expected behavior

It should not split the line into two half lines.
