Summary

When porting an antd datepicker CCv1 component to CCv2, I noticed that interacting with popovers managed by such components causes the Streamlit sidebar to close.

This only occurs in the mobile layout and only with CCv2. Interaction with the widget itself inside the bidi-component container works as expected, but interacting with the popover rendered at the top level of the DOM immediately closes the sidebar.

Here's an example:

The popover is rendered at the top level of the DOM, as a sibling of the root element:

I may send the component later, it is a bit messy at the moment since i'm still getting the hang of the new component api.
