Multiline error and warning messages overlap, in the Debugger.

The lines separate when the mouse pointer is moved over the messages area.

It doesn't happen in:
- v4.0.3.rc1.official [2d74ee0e5]
- v4.0.2.stable.official [7a0977ce2]

Because they don't show multiline messages. The messages appear on a single line.

### Steps to reproduce

- open the attached project: [issue, overlapping multiline text.zip](https://github.com/godotengine/godot/files/11472223/issue.overlapping.multiline.text.zip)
- run the project
- open the Debugger (at the bottom left, to the right of the Output button)
- open the tab: Errors

### Observed

The multiline error (red) and warning (yellow) messages are overlapping.

### Expected

The error/warning messages shouldn't overlap.

They become "unoverlapped" when the mouse pointer is moved over the overlapping messages area.
This is probably how they should appear as soon as the Debugger, Errors tab opens.
