Rustdoc line number desynchronization on iPhone Safari

[pali6]

On iPhone Safari 15.1 (and possibly other mobile browsers, I am unable to check EDIT: Android browsers do not have this issue) in the source view code lines get line wrapped which causes the line numbers to desynchronize from their lines. In some cases multi-digit line numbers also get line wrapped which causes further desynchronization, though from my checking this currently happens for docs hosted on docs.rs but not on doc.rust-lang.org/std. This issue also means that clicking on source links in documentation leads to completely unrelated code as the links are to the line numbers and not the lines themselves.

This issue does not happen on Windows browsers I tested when I manually shrink the window to be approximately as narrow as the mobile browser. I have not tested the issue with computer version of Safari.

I don't have an iphone so I won't be able to check what's going. Does someone on the @rust-lang/rustdoc team has an iphone by any chance?

I've got one and will check.

I was unable to reproduce on iPhone 15.5. The lines don't wrap at all, which is expected behavior.

It looks like the latest iOS version is 15.7. I'm upgrading to that now. @pali6 would you mind upgrading to 15.7 as well and seeing if it still reproduces for you?

[pali6]

That indeed fixed the issue. My bad for not staying updated.

No worries! Thanks for taking the time.
