Runestone Issue: Parsons blocks don't fit space when you add left numbering in Python.

[barbarer]

I was in py4eint on page https://author.runestone.academy/ns/books/published/py4eint/funcWithStrsAndConds.html. I added left numbers to the first Parsons problem - (labeled 5) and now the blocks don't fit in the source space on the left. The line number are much bigger than the code font.
