Section navigation appears to be broken

[mook-as]

It looks like expanding the navigation menu is sort of broken.

Steps to reproduce:

1. Navigate to https://docs.rancherdesktop.io/
2. While still on the Getting Started → Introduction page, switch to a different version using the version dropdown at the top.
3. Without navigating to a different page, expand the User Interface heading, and then then Preferences sub-heading.

Expected results:

The Preferences sub-heading expands.

Actual results:

The toggle to the right of Preferences changes from ▷ to ▽ but no additional headings show up.

Additional information

If we switch to any page under the User Interface section before switching versions, the sub-headings show up correctly.

I'm not sure how to determine the deployed version of the docs site, but it's probably at 042b5e0.
