Summary: The standard merge_patch (aka RFC7386) mechanism that we used before removes the key-value pairs from the original object in case if the patch has a `null` value. And we don't need it there because we should pass this null value down to the mounting layer to clean up this prop there. Besides that, the patch should not be recursive because props are not divisible. Changelog: [Internal] Fabric-specific internal change.
