In the Theme Editor the option to disable navigation menu icons is not respected in mobile menu (or missing in the options for the mobile menu).

I have logged this as a bug, but it may well be that this is intentional.

Do you have any feedback if this is accepted as a bug or is considered intentional?

Because, if it ist intentional this would force me to pick a meaningful icon for every menu item, if I can not turn them off entirely.

Its an open bug at present, but it does indeed seem it is a bug

Ok. Thanks.
I guess I'll hide them using custom CSS in theme editor for now and check back sometime to see if it's fixed.
