Investigate anomalous DragAndDropFIeldArray and react-beautiful-dnd behaviour

From https://folio-project.slack.com/archives/C210UCHQ9/p1624273852159300

seeing some interesting behaviour on folio testing/snapshot with react-beautiful-dnd. As part of the work for ui-dashboard I created a final form component:
DragAndDropFieldArray. As things stand this works great locally, and also in systems with only ERM modules present, but on snapshot etc we see a behaviour where dirty fields get reset when dragging.
 
Thus far I've been unable to replicate it locally, but I would presume it's something to do with mismatched/duplicate versions of either final-form (or any of the final-form related deps) or react-beautiful-dnd.I can see ui-requests pulls in react-beautiful-dnd: ^11.0.5, but doing that locally I couldn't replicate the issue, so that may be a red herring.
 
Is this behaviour anyone has seen before/knows where to start debugging? A cursory sweep of the relevant github issues tabs returned nowt.

To see the issue: * https://folio-testing.dev.folio.org/dashboard/DEFAULT/create - select "ERM Agreements" from the "Widget definition" dropdown

• In "Results display", add 2 columns
• Change second column to "start date" with a new label
• Drag 2nd column to first in list
• Notice dirty fields have been overwritten
