Virtualizer component or virtualising props on collections components

[mJarsater]

Provide a general summary of the feature here

In #5912 and https://react-spectrum.adobe.com/releases/2024-07-22.html a "custom" virtulizer component is mentioned, but there is no documentation for how to implement/use it. We have multiple ComboBoxes/Selects that have a lot on items (1000+) and without virtulization they quickly become very non performant. Therefor we would love a Virtualizer component with a predictable API from react-aria-components.

🤔 Expected Behavior?

Some type of Virtualizer component would be great. If this is to complex and needs to be done "under the hood" it would be great if there were props exposed on the ListBox from virtualizing.

😯 Current Behavior

No virtualization is done out-of-theb-box and there seems to be no docs on how to achieve it.

Hey, sorry about that, we plan to release docs covering the RAC virtualizer in the future but just haven't gotten the time due to other priorities. Can you try doing something like this: https://codesandbox.io/p/sandbox/pedantic-black-vrd8rh? Otherwise, you can look at some of our stories for an example of how to use UNSTABLE_Virtualizer for now.
