bug in dropdown menu on doc.owncloud.com

WHAT Needs to be Documented?

The table of content on the left side drops down and snaps back in when I click on the little arrow. It also drops down when I click on the text but when I click again it only snaps back in on some of the headers.

WHERE Does This Need To Be Documented (Link)?

(https://doc.owncloud.com/server/)

WHY Should This Change Be Made?

On "Admin manual " it works perfect. But when I click "The ownCloud Documentation" it only drops down but when I click again it doesn't snap back. It happens on a lot of the headers in the docs that they only drop down. It would be easier to work with the docs especially on small screens.

Steps to reproduce:

1. Visit https://doc.owncloud.com/
2. Navigate the mouse to the table of content on the left side.

3. Click on the Text (Installation) (not the arrows) in the dropdown-menu to open them and clicking again to close them

Expected behaviour:

dropdown should close when clicking on the headers

Actual behaviour:

dropdown only closes when clicking on the little arrow in front of the headers

I tried it with Google Chrome (Version 87.0.4280.66 (Official Build) (64-bit)) and with Mozilla Firefox 83.0 ((64-bit)) Happened with both.
