A new hover card component, just like tooltip, it will be a card instead of tooltip.

TIL: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/:interest-target

This is experimental and not a standard yet, but the interesttarget explored with a small JS sim can be considered in the existing ot-dropdown component. Doesn't make sense to ship a new component.
