I am using a custom theme with blank as parent. Everything works well but I noticed that on responsive screens the hamburger menu seems broken. When I click on it nothing happens while I expect the navigation menu to show up.
The version of the Magento installation is 2.2.5 I tried inheriting the menu.js and extended only the toggle function but still it does not work
Is there anyone who has experienced the same issue and can give some advice?
!UPDATE! event handler is not attached to the element! It is though attached only on login screen and there the button works properly
