Opening an anchored link scrolls to the wrong place in Safari on macOS

[wilkinsona]

I'm using Safari 15.5 on macOS Monterey (12.4). When I open a link like https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto.webserver.use-behind-a-proxy-server, the docs scroll to the wrong place:

Chrome and Firefox on the same OS are not affected so it appears to be a WebKit/Safari-specific problem.

Seems to be javascript related.
