The space looks fine, but a strange bug occurs.

When I recreate the pull request with the change recommendation as described in the issue and then enter another change reco in the first line, lines 1 and 2 overlap.

To make sure this is a bug that only occurs in this pull request, I tested it on the current live version as well as on the internal 4.3-transitional branch. The problem does not occur in either version. I suspect there is a connection to this pull request.

To reproduce the error, a change reco must be entered in the first line. Whether words are deleted or added, the error occurs in

Here is a screenshot of the error:

Found other points, that need to be fixed:

1. Change Recommendation on two or more lines results in invisible lines. Reproduction: Select first two lines for change reco and delete a word. Save it. Second line won't be visible anymore. Here images:

Content before change reco:

Content after change reco - line two is invisible.

What should happen: All lines should be visible.

2. Broken change reco from current change request appears again in content below the change recommendation:

--> What should happen: The broken change recos should not happen.
