## Your Environment

| Tech | Version |
|--------------|---------|
| Material-UI | |
| MUI-datatables | 2.13.2 |
| React | 16.9.0 |
| browser | All |
| etc | |

Start by reproducing the filter-chip flow in MUI-datatables 2.13.2: focus a chip with Tab and press Enter. Inspect the filter-chip implementation and its keyboard behavior; done means the focused chip closes and the filter is removed when Enter is pressed.
