Mobile Navigation on Plugin Handbook doesn't scroll

[garrett-eclipse]

Hello,

Minor issue with the Mobile Navigation on the Plugin Handbook. If you expand enough items you won't be able to access the lower ones unless you collapse again. It would be nice if the menu itself would scroll on overflow.

Thanks

In 9643:

Developer: Allow scrolling of sidebar menu on mobile so items at the bottom don't end up offscreen and inaccessible.

Props garrett-eclipse, coffee2code.
Fixes #5122.
