[REVIEW ONLY] Removes line height setting

This may not be the fix we want, but it removes the line height setting as an approach for #8519 and some of the behavior noted in the comments of #8523.

Removing the line height setting entirely seems like the easiest solution at this stage and we could try to resurrect it for a future release.
