Long code `blocks` overlap with normal text

Steps to reproduce

Create a node with the following text:

**Lorem Ipsum** is simply dummy text of `the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s`

Expected result

Text and code blocks should coexist nicely

Actual result

They donā€™t. Instead, there is overlap between text in different rows. See screenshot:

Environment

I see this on Ubuntu, browsing with Chrome. I see this both with and without PowerPack enabled. I donā€™t have other third-party extensions.

Thanks, I can repro this bug.
