Combination of `anyOf`/`allOf` does not retain the correct option defaults

[linas-vii]

Prerequisites

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

Description

When having a combination of anyOf/allOf, the generated default option for anyOf is not retained correctly from the form data.

See this link in CodeSandbox for an example.

Playground example

Steps to Reproduce

1. Open the example.
2. Choose a variable and change it from Baz to Bax.
3. Change tabs from Form to JSON, and back again from JSON to Form.

Expected behavior

The option for a variable selected is retained between the tab changes.

Actual behavior

The option for a variable selected is always changed to the first option (in this case Baz).

Version

2.4.0

Additional details:

I tried to debug this issue, and there are certain points which might be the cause, but please correct me if I have misunderstood something here:

• In core/src/util.js:224, getMatchingOption is being passed formData as undefined, shouldn’t it just pass the formData as it is?
• In core/src/util.js:1179, shouldn’t the option be resolved first with resolveSchema(option, schema, formData) in order to have all $ref's resolved before performing validation at core/src/util.js:1222 and core/src/util.js:1225?

I reproduced this issue using only allOf (without combining it with anyOf): Playground.

I copied the example from the official Json Schema documentation but added defaults.

Expected: Form should show defaults for both addresses. Actual: Form only shows defaults for the address not using allOf.
