[FIX] web: fix autoMoreMenu with no-hamburger option

On small viewports, and with the "Same as desktop" option enabled on
header, The "autohide menu" adaptation is disabled and overflowing
menu items are visible.

The goal of this commit is to fix this behaviour by keeping the
"autohide" feature enabled on expanded navbar.
