x/pkgsite: paragraph links work incorrectly on mobile

[handsomefox]

What is the URL of the page with the issue?

https://pkg.go.dev/runtime#SetFinalizer

What is your user agent?

Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Mobile Safari/537.36

Screenshot

What did you do?

1. Got a link to a package, linking specifically to a paragraph (specifically, a function in that case)
2. Opened the link using Chrome

What did you expect to see?

I expected to see my browser opening the link at that specific paragraph

What did you see instead?

The browser opened the link correctly, then jumped to the top of the page

Using links like: https://pkg.go.dev/runtime#:~:text=func%20SetFinalizer%20%C2%B6,will%20free%20obj does work.

@suzmue I ran into this today. I can reliably reproduce it. Could you use any help investigating and/or fixing it? I'm happy to dig into it further, but I could some help getting started. Thanks. 😊

See this issue still too, clicking in the address bar and then pressing enter scrolls anchor into view. but only after this manual intervention.
