Add to keep an element in the DOM when element in focus, or other case

[pan-alexey]

Hi.

We are implementing a table with a virtual list and have encountered a problem with keyboard navigation. During scrolling, the element that is currently in focus can be removed from the DOM, causing us to lose focus.

Is there a way to specify that this focused element should not be removed from the DOM tree, so that the browser does not lose focus?

Yes, you can use rangeExtractor to keep the focus index always mounted https://tanstack.com/virtual/v3/docs/api/virtualizer#rangeextractor
