Unexpected linebreaks in some code outputs

[jbrightuniverse]

In a few places in the current build, code is linebroken in unexpected spots.

E.g. second code output in 4.7.3, first code output in 5.2.4.

This is not a problem in the .ipynb files, and when rebuilding the lectures, the resulting HTML also does not have this issue (for 4.7.3 at least). 5.2.4 has the linebreak in a different spot when rebuilt.

For example, 5.2.4's first code output right now looks like this:

And then when rebuilding:

There are more such issues in other lectures as well.

Just to add to this, it seems the specific blocks that have linebreaks differ between versions i.e. a block with no linebreak in one publish has a linebreak in the next/vice versa. At least I noticed this between the current 1.6 publish and the 1.7 PR.
