Editing view layout issue at exactly 768px resolution

[rioksane]

When logged in as editor in Volto Light Theme site and the screen resolution is exactly 768px, the layout breaks slightly. Left menu goes over content and there is too much empty space on top.

You can easily test this in https://demo.plone.org/
Volto 18.1.0
Plone 6.1.0b1

This issue does not appear in 767px (using mobile layout) or 769px (using desktop layout).

PS: In vanilla Volto the problematic resolution is 767px
