[Bug] Side Nav not updating when link is followed to different page

[davidkonigsberg]

Describe the bug

When a link is clicked and redirects to a different page, the side-nav still shows the original page selected even though the user is now on a different page.

To reproduce

1. Go to these preview docs: https://sayari-analytics-preview-8d472466-ecb5-423d-88b4-fcc2ee310a0a.docs.buildwithfern.com/
2. Navigate to "Sayari Library" -> "Ontology" -> "Entities"
3. Click attributes link "additional_information"
4. Done, you are now on the attributes page, but entities is still selected in the side nav

Expected behavior

The side nav should reflect the page currently being displayed

I find that this only happens when the link is to a named anchor or id on a page. That is, when it's a link like /something#heading_id. Otherwise, the side nav updates as expected.

You can see an example of this on Fern's own docs. Go to https://docs.buildwithfern.com/generate-sd-ks/generators/type-script-browser-sdk and scroll to the bottom. Click the link there to /generate-sd-ks/generators/type-script-node-js-sdk#configuration-options and see that the side nav does not switch to the TypeScript NodeJS SDK.
