A MR adds two consecutive blank lines. If I select them and press the button to add a suggestion, I get (as expected) a suggestion block like:
````
```suggestion:-1+0
```
````
Since consecutive blank lines are silly, I want to suggest reducing this to one blank line:
````
```suggestion:-1+0
```
````
However, GitLab incorrectly renders (and perhaps *applies*) this as:
```diff
-
-
```
...that is, showing to remove both blank lines and replace them with nothing, when the suggestion still contains a blank line.
A correct rendering would be:
```diff
-
```
See e.g. https://gitlab.kitware.com/cmake/cmake/-/merge_requests/10883#note_1673338.
Note, I'm not sure if this works correctly if the suggestion has more context (i.e. starts and ends with non-blank lines).
