You're right. This has nothing to do with LWP. Please don't be rude
like that the *next* time. This list is strictly for *development* of
LWP, not support of same nor support of other web-ish stuff.
But since you've already burned your bridge before you got to it,
here's your answer...

It's not anomaly. An internal redirect (one beginning with /) is
handled entirely within the server. As such, there's no way to tell
the browser to scroll to #symbol once the page is delivered. An
external redirect (one beginning with a protocol) is sent as-is to the
browser, and now the browser has access to the scroll-anchor.
Live with it.
