Correctly nest sub-menu for h3s inside h2 list item

[michapietsch]

Observed behavior:
An ul with H3 links is nested inside the parent ul and as a sibling to the li containing the link to the H2.

Fix:
The sub-menu for H3s is now nested in the same way H2 sub-menu already are.

The former incorrect nesting also constitutes an a11y issue.

Thanks for the effort! Can you guide us to an example of this change in action? A before/after comparison would be even better!

[michapietsch]

Yeah, sure!

Before:

For the third level heading "Relation to Custom Elements" the containing ul is a direct child of the parent ul.

After:

Now the li contains the a as well as the sub menu ul. For sub-menus for second level headings like "Introduction" this is already handled correctly, as you can see at the top edge of the DevTools DOM tree visualization.

Hope that helps! Please let me know, if you have any more questions!

Right, thanks for the fix!
