Controls bound to complex values not updating after patch

[colscott]

Given data:

const data = {
  dateRange: { start: 20230401, end: 20230410 }
}

Control bound to dateRange

<date-range bind="/dateRange"><date-range>

Patch dateRange:

myForm.patch({ dateRange: { start: 20230606, end: 20230616 } })

The date range control is not updated.

Only controls matching the JSON pointers are updated:
"/dateRange/startDate", "/dateRange/endDate"

Need to also update controls matching "/dateRange".
