Popover content overflows when browser window is too small

[erlend-skarpnes]

Describe the bug

When using a Popover in a window where the content is taller than the window height, the popover itself shrinks to maintain some space under it, but the content inside the popover overflows.

Steps to reproduce the bug

1. Open a popover with a lot of content
2. Shrink the height of the browser window until the popover starts shrinking.

Can be reproduced in your storybook:

Expected behavior

The popover should contain its content when it overflow, for example with a scrollbar (easy solution) or something more sophisticated (pagination?).
