I'm using a T4 Template Blank on a Joomla 3 site, since I'm preparing to upgrade to Joomla 4. While building the template, I just ran into a strange issue. When I switch on offcanvas navigation, the toggle bar appears twice. Both, the offcanvas menu and the mobile mega menu show up. Do I have to switch off the mega menu manually when I want to use offcanvas menu?
