Describe the bug
Code blocks, when very long, are allowed to overflow outside of the contain class.

Reproduction steps
Steps to reproduce the behavior:

1. Create a code block with a really really long line, so long that the text is larger than the container (maybe copy this line?)
2. Look at code block

Expected behavior
The code block does not overflow outside of the box

Additional context
The solution was included in the picture, and also below:

pre {
    overflow-x: scroll;
}

Make sure to test it a variety of cases. (I also might make a PR myself to fix this issue since you know, I already got the solution right above)
