Documentation pages overflowing the viewport (code blocks)

[0x5c]

As pointed out by a user named @Pearl on the discord server, some documentation pages overflow out of the viewport, and without scrollbar, rendering them impossible to read.

By investigating further, it appears that the pages with overflow are the ones with code blocks containing lines wider than the content margins. This seems to cause the margins to be pushed further out, allowing the content to extend out of the screen.

This problem is more apparent on small or narrow screens, like mobile phones.

#67 is related, but seems to only fixes part of the issue, as mentioned by the author.
