Description
### Feature Description
Please, add support for rich tooltips (popups).
They're [described](https://m3.material.io/components/tooltips/overview) in M3 standard.

Existing tooltip and menu components are not enough for feature-rich web apps.
### Use Case
* Hover/click a table cell or any other element to display more info via a custom component or a template ref.
* Use it as a menu that won't be closed after clicking a menu item
Contributor guide
Research direction
Start by reviewing the linked M3 tooltip specification and the existing tooltip and menu components. Define the scope and API for showing a custom component or template from a hovered or clicked element, including menu behavior that remains open after an item click; done means these use cases are supported.
