when openning https://docs.substrate.io/tutorials/collectibles-workshop/ the navigation tab is lost

[gui1117]

when running tutorial: https://docs.substrate.io/tutorials/collectibles-workshop/ the navigation tab on the left collapse and the tutorial steps doesn't show up in the navigation.

The only way to navigate is through the button next and previous this is not so good.

Better would be to have it in the navigation bar so I can resume/skip parts/looking ahead/looking back in a tutorial easily.
