Navbar Menu Items displaced upon browser resize

Hello,

When I resize the browser there is a small stage between the mobile menu button and the normal layout, where the menu items are moved to a position at the bottom of the navbar.

I cannot figure out how to fix this.

To the left I have the ‘Customize’ toolkit. To the right the website’s sidebar.

Hi there,

I have tried to check your site but I can’t seem to replicate the issue. See screencast in the Secure Note.
