oneOf with "object" types - impossible to replace Option 1

[naorgu]

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

When using a json schema with oneOf where the possible types are object, Option 1 properties cannot be removed - when choosing a different option, Option 1 properties remain in the json output. See Playground reproducible

Steps to Reproduce / Actual behaviour

1. Create a json schema with oneOf with object types
2. Switch to Option 2
3. Option 2 properties added, Option 1 properties remain in the json output
4. Switch to Option 3
5. Option 3 properties added, Option 2 properties deleted (as they should), Option 1 properties remain

Expected behavior

1. Create a json schema with oneOf with object types
2. Switch to Option 2
3. Option 2 properties added, Option 1 properties deleted
4. Switch to Option 3
5. Option 3 properties added, Option 2 properties deleted

Correct behaviour can be found in the json-editor playground here
