[details] content overflows if height is too small

[jouni]

Description

If you give <vaadin-details> an explicit height that is smaller than the content, the content overflows without a scrollbar.

Expected outcome

I would expect the content area to become scrollable.

Minimal reproducible example

<vaadin-details summary="Details 1" opened style="height: 50px;">
    <div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Cum iste ex provident accusamus laudantium omnis, perspiciatis
      illo neque minus excepturi, laborum alias aperiam officiis vero aut quas esse laboriosam corrupti.</div>
</vaadin-details>
