Problem Statement/Rationale

It is currently not possible to edit a document with a nested _id field in a document view

Steps to Reproduce

Try to edit a _id field nested under the data field

Expected Results

You can change the field value

Actual Results

Field is not editable

Additional Notes

hadron-document currently marks field as read-only if the field key is _id, whereas it should probably also check that the field is a direct child of the root as an additional condition for marking a field read-only
