Bug description

When using Instant Loading, selecting a link in the table of contents, navigating away, returning, and then selecting the same toc item does not jump to the id until the second click.

I've confirmed this in Chrome, Firefox, and Edge.

Fixed in 485fa76fbc086f9b99f2291fbc0c6052c5a32d79! Thanks for the excellent issue and reproduction, that made isolating and fixing the issue really easy. The problem was that the pathname change was not properly detected, which is now ensured by the document$ subscription and the double switch map on location$. The comment explains how it works:

Perfect issue! Thanks for taking the time.
