Bug – The main menu disappears

Problems with the main menu if you have activated the sticky header and use the menu layout with the logo on the left and menu on the left at the bottom of the logo.

When the sticky header is visible and you resize the window from desktop-size to tablet-size and desktop-size again.

And you return to the top area of the page, the main menu has disappeared and the only way to reappear it is to reload the page.

The problem is also reproducible if you use a tablet and you rotate it several times.

Best regards
