Description

When using CSS max-width: 50% on a md-menu, the inner div.items inherits the max-width and applies it itself, which leads to wrong display.

Research direction

Start with the linked Lit playground reproduction and the md-menu styling entry point, focusing on the inner div.items element and its max-width behavior. Confirm the issue by applying max-width: 50% to md-menu; done means the outer menu respects the constraint without incorrectly constraining div.items.
