When a crate name is long, the "See all <crate name> items" heading in the sidebar overflows its box.

E.g.: https://docs.rs/trillium-caching-headers/0.1.0/trillium_caching_headers/index.html

Note that Crate trillium_caching_headers above it does not overflow, because it has word-wrap: break-word. Perhaps we should consider applying that to everything as a default (since we often have this type of overflow problem), and override that default in specific places, like code examples, where we'd rather have a horizontal scroll.

Another recent example of overflowing a box was #89972 (and a fix in #90018).
