Steps to replicate the issue (include links if applicable):
<syntaxhighlight lang="javascript" line linelinks="ą"> a b c d </syntaxhighlight>
https://test.wikipedia.org/wiki/Linelinks
Then click the line numbers.
What happens?:
The links navigate to a URL like https://test.wikipedia.org/wiki/Linelinks#ą-2, but do not highlight the selected line, or scroll to it.
What should have happened instead?:
The links should work. If that's impossible, then there should be no links, and the limitation should be documented.
