How can we reproduce this issue?

The issue can be reproduced in this Storybook story (see attached video): https://opensource.adobe.com/spectrum-web-components/storybook/index.html?path=/story/picker--custom

Anecdotally, this seems to happen more often when a menu item that would otherwise be hidden by overflow is selected.
