Public DRM does not render correctly, is hard to navigate

Expected Behavior

I want to discover the layout rules in human-readable form without knowing the rule numbers up front.

Actual Behavior

When I land on the readthedocs.io web page, the menu entries do not have any menus suggesting sub-entries or any depth.

I click through them and by sheer luck end up something that says "Design Manual", under Physical Verification. An arrow has now appeared next to that menu entry but I don't notice it at all.

I see in the list in the right pane 7.0 Layout Rule Description, so I click that.

I am now here. There is nothing clickable. Where do I go?

With the help of others I have learned that if I now expand the menu item, I can see all the relevant sub-documents. But I had to get two people to help me.
