A webdev in our company said:

This is because NodeBB uses a hidden class to hide the opposite value (lock/unlock) so focus is lost when going over the hidden element.

This could be fixed by using a hidden attribute on the <li> element but the toggleClass code is in NodeBB core not the theme code.

There is a need to fix this because accessibility by keyboard is important for some disabled or without-mouse users.
