Nested oneOf and allOf when using oneOf with @JsonSubTypes

[ghovhannesVM]

Describe the bug
When I use @JsonSubTypes with @Schema(oneOf = {..}), the model schema shows infinite nested oneOf and allOf. When I remove @JsonSubTypes from the parent model, everything works well. Am i doing something wrong or is this expected behaviour ?

Expected behavior
The expected behavior is to show only the oneOf field. After selecting one of the child classes, it should stop expanding.

This is still broken in 2.6.0

We ran into a similar (maybe the same?) issue when trying to use polymorphic types, like:

@JsonTypeInfo(use = NAME, include = PROPERTY, property = DISCRIMINATOR_PROPERTY)
@JsonSubTypes(
    Type(value = Activate::class, name = ACTIVATE)
)
@Schema(
    subTypes = [Activate::class],
    oneOf = [Activate::class],
    discriminatorProperty = DISCRIMINATOR_PROPERTY,
    discriminatorMapping = [
        DiscriminatorMapping(value = ACTIVATE, schema = Activate::class)
    ]
)
sealed interface PolymorphicEvent {
    @Schema(requiredProperties = [DISCRIMINATOR_PROPERTY])
    @SchemaProperty(name = DISCRIMINATOR_PROPERTY, schema = Schema(allowableValues = [ACTIVATE]))
    data object Activate : PolymorphicEvent

    companion object {
        const val DISCRIMINATOR_PROPERTY = "type"
        const val ACTIVATE = "ACTIVATE"
    }
}

Defining this in 2.3.0 would work, but totally broke our Schema view in SwaggerUI after 2.5.0, where the oneOf definition just references itself recursively forever. (This might even be worth a second issue)

I have the same probleme in 2.6.0
