Multi-line title spaced incorrectly

Ubuntu 14.04, GIT commit: 2f31c34

1) new score, enter a title
2) double click title
3) add more lines of text

Result: the lines are too closely spaced. Also, when you first hit "Enter" at the end of a line, the cursor is too small, which I guess is a symptom of the same problem.

4) hit Esc to leave edit mode

Result: now the lines are more widely spaced - too wide, perhaps?

There are other issues involves newline characters in text elements - see for instance #34526: Special characters and newlines are not pasted correctly in edit mode, #36271: If text contains newline, "Copy/Paste" operations add unrelated characters, and #36276: Deleting a line break in the middle of text automatically adds one at the end. But I think this one is different, and fairly new.
