Related Issue

as part of #128 / #300 , fixes an immediate error now identified as #331

Summary of Changes

1. fallback to make sure currentPage is found, but not sure if a logic issue?

[hutchgrant]

The bug is only present during my testing when you load page with an anchor tag in the link.

In the process of trying to replicate this I found another bug.

This link will scroll the page down when it should not. This behaviour is present on all pages.

edit: added issue #309

[thescientist13]

It looks like part of the issue is that Netlify is adding a trailing /, which is partially interfering with the matching logic, hence why sometimes a currentPage isn't found.

Might be worth making an issue for this, maybe thinking of a way to inject some sort of `CURRENT_PAGE_ constant / environment variable or something? Or ideally getting it from the graph somehow.

Maybe doable as part of #305 or #299 ? Or maybe just needs it own issue.

Made a formal issue for this and putting into the next project to find a proper solution for this (the trailing /)

Also seems related to #310.
