if-then in allOf is not working when additionalProperties is set to false

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

Let's take an example: playground

The schema has "additionalProperties" set to false and "abc" enum property, then we have "allOf" section with 2 conditions for "abc", each of them should add some new, required property, but it is not rendering, unless "additionalProperties" is removed or set to true. Even though they are not shown, the validation is executed against them and it fails.

Expected Behavior

The schema from above should add properties that are conditionally configured in "allOf" section even when "additionalProperties" is set to false, so they can be filled.

Steps To Reproduce

1. On this playground
2. Select "value1" or "value2" in "abc" field
3. Execute validation
