Label text appears to be cut off below the staff when it shouldn't

Here is an example, just look at the first cell of: https://www.maria.cloud/gist/95f53d70ebd8fcb68d5657c4b6973602

And a screenshot just in case the demo is broken:

Notice that the bottoms of "g" and "p" are cut off. Changing the y attribute doesn't seem to fix the issue. I believe that line-height as an exposed attribute might be helpful to resolve this. This issue also is present in normally rendered text, a la (text "graph")
