Links in left sidebar are active even when not on linked page

[Arad1el]

What happened?

The logic for the left sidebar links sets them as active when the name of the current page matches the name of the linked page.
This means that, given two pages with the same name, where only one should appear in the left sidebar, the link is active on both of those pages.

In the minimal reproducible example:
/p/imposter/ does not reference the menu, but the link is active
/imposter/ is the page that the link refers to

I've already made a PR for this issue, so that it instead compares the URLs of the pages: #1153
