InfiniteList renders duplicate keys and shows unstable sort results

[emanuelfrua]

When using InfiniteList with a DatagridConfigurable and server-side sorting, I occasionally encounter this warning:

Encountered two children with the same key, 716a838d-684f-4588-a941-50414c5fce8d.
This happens even though:

All records have a unique id

The backend returns correct, paginated, sorted, non-duplicated data

The sort is handled correctly by the backend

The list sometimes shows records in the wrong order after switching sort direction, or re-renders the same row multiple times, especially on the first scroll.

When I switched to List instead of InfiniteList it works fine.

Thanks for your report. However, without the ability top reproduce this error, we can't investigate it. Can you please join a repro?

@fzaninotto Hi Francois, yes, of course
