Error blockquote doesn't scroll properly on iOS

• I have checked the latest main branch to see if this has already been fixed, in this file:
  • No, due to #16

URL to the section(s) of the book with this problem: https://rust-book.cs.brown.edu/ch04-02-references-and-borrowing.html#data-must-outlive-all-of-its-references

Description of the problem: On iOS, the horizontal scrolling for this particular error code block is broken. A horizontal swipe in either direction will only get you maybe 20px of scrolling. It only seems to be an issue in this one block, other Rust error blocks on the same page work fine.

Suggested fix: No idea, sorry. I'd investigate if I could build the book…

Confirmed that I could reproduce this. I narrowed the issue specifically to the permission stack that appears in the blockquote ("we will abbreviate them as dots like"). I genuinely have no idea why that element is interfering with mobile scroll behavior -- I will continue to investigate.

I'm not sure if it's weirder or not that you also get this behavior when using the horizontal scroll thumb! Over the years, I have seen odd scrolling behavior with gestures or the scroll wheel. But I don't think I've ever seen the scroll thumb behave this way. Super strange. I wonder if it's a WebKit bug?
