Drag row exception when row virtualization is true about material-react-table

[helt]

It appears like the first argument rowOrVirtualRow is sometimes empty during drag.

If we look at virtualRows and rows, we can observe that in the moment when dragging starts, virtualRows grows by a single item, which is undefined. I suspect that packages/material-react-table/src/hooks/useMRT_RowVirtualizer.ts to be the origin of the bug, specifically the rangeExtractorCallback.

If i disable the custom rangeExtractor in packages/material-react-table/src/hooks/useMRT_RowVirtualizer.ts, then dragging works as I would expect. However, there must be a reason, why it is there in the first place.
I dont understand why there needs to be an additional index created, and why it should be different from the rowindex of the dragged row, I dont know how to fix.

@KevinVandy You know where to test, if my fix breaks the current implementation of the rangeExtractor? Then I can submit a PR.
