When "searchOpen" option is set to true and pressing escape key closes the search bar.

When "searchOpen" option is set to true, and pressing the Escape key is closing the search bar. Is it possible to open the search bar even if we press the Esc key?

## Expected Behavior
It should not close the search bar if we press the escape key.

## Current Behavior
Set the "searchOpen" to true. After rendering in UI, press the Esc key which closes the search bar.

## Your Environment

| Tech | Version |
|--------------|---------|
| Material-UI | 4.6.1 |
| MUI-datatables | 2.12.4 |
| React | |
| browser | |
| etc | |

Start with the linked CodeSandbox reproduction and trace the searchOpen option together with the Escape-key behavior in the search bar. Done means pressing Escape while searchOpen is true no longer closes the search bar, while the reported behavior remains reproducible for other cases.
