How to disable MenuBar animations on small screens (>420px)

Currently, MenuBar’s SubMenu items are appearing at the bottom of the screen when screen width or height goes under 420px. How can this be disabled? I would like to keep MenuBar as a dropdown with SubMenu items even on small screens. Thanks.

I don’t think it’s possible. A similar request was created for the select: Disable mobile styles for vaadin-select-overlay · Issue #6777 · vaadin/web-components · GitHub
