React Warning "each child should have a unique "key" prop

[bjonen]

When running the basic table example from https://dash.plotly.com/datatable, there is warning in the console:

Warning: Each child in a list should have a unique "key" prop

I am running dash inside docker with versions:
dash: 1.18.1
dash-table: 4.11.1

Seems to be duplicate of plotly/dash#1433
