…ay trigger a partial page reload (elastic#59476)

The `react-beautiful-dnd` library, upgraded during the `7.6` stack release from
`10.0.1` to `12.2.0`, includes a breaking change to the way [errors are handled](https://github.com/atlassian/react-beautiful-dnd/blob/v12.0.0/docs/guides/setup-problem-detection-and-error-recovery.md)
and recovered. As a result of this change, an uncaught error may trigger a
an effect that feels (from the perspective of a user) like a partial page
reload.

The most common condition where this can occur is when dragging entries to the
Timeline while data is loading, per the animated gif below:

## Reproduction steps

1. Navigate to the Hosts page
2. Open the Timeline
3. Drag a host to the Timeline
4. While data is still loading, drag a different host to the Timeline to create an `or` query

**Expected Result**
* The page does not appear to reload
* In development mode, a single error is logged to the JS console

**Actual Resluts**
* The page appears to reload
* In development mode, two errors are logged to the JS console

**Error 1**
