Clicking on a sub section in the docs highlights the wrong section

Tthere's a bug in the left navigation item highlighting (tested in Safari 15.4 and Firefox 99.0b7). When I click any x.y subitem, the highlighted item in the nav is x.y+1 (or one of its child element). Here's how to reproduce it:

  1. Go to https://sdk.play.date (you're redirected to Inside Playdate)
  2. Click on 3.3 Compiling a project in the left nav
  3. Item number 3.4 is highlighted.

Thanks for letting us know!
