Steps to reproduce the bug: - Go to the website edit mode. - Choose the 'vertical' template header. - Select 'off-canvas' in the 'mobile menu' option of the navbar. - Bug: On mobile view, the menu links are not clickable. This is caused by the addition of the "order-first" class to the navbar by commit [1], which causes the menu to be placed behind the backdrop in mobile view when off-canvas is activated. This only happens with Firefox, and there is likely a difference in how Chrome and Firefox handle the "order" property based on the positioning of elements.
