This snippet actually does something useful, although it might not look like it is a case at the first sight.

It truncates short descriptions in the list of items such as in search or at the bottom of the module page. Without this script, horizontal scrolling appears on smaller viewports (ignore the terrible fonts, this is many-years old version of chrome being dumb):

There’s not really a good way to preserve this functionality without javascript, because that’s how HTML tables work.

[mahkoh]

All the better. Whoever thought that hiding information from people with small screens was a good idea should be punished by having all descriptions removed from their rustdoc searches.

An alternative to the scrolling is breaking like this.

Could you amend the commit message to contain more details? As it stands it doesn't even contain a reference to the issue in question.

[mahkoh]

Done.

Another solution is to use CSS which has a built in feature to cut off overflow with ellipses.
text-overflow: ellipsis;
Why are we simulating CSS with a terribly slow JS solution?

[nagisa]

Because that doesn't work on tables.
