oneOf not using given data

[ibot3]

When using a oneOf structure to select different schemas, the given data value is not used by the form.

This for example applies to the oneOf example here:

type: object
title: An object with a oneOf
oneOfLayout:
  label: Select a subschema
oneOf:
  - title: oneOf 1
    required:
      - str1
    properties:
      key:
        const: oneOf1
      str1:
        type: string
  - title: oneOf 2
    required:
      - str2
    properties:
      key:
        const: oneOf2
      str2:
        type: string

When key is changed, the change is not reflected in the form, instead the "key" field stays empty.
This makes it impossible to use this form schema in a scenario where given data should be edited.

This behavior can also be observed in the editor available on the docs page.
