AllOf is wrong rendered

I have defined the following schema in my components:

            "test1": {
                "type": "object",
                "properties": {
                    "useText":
                    {
                        "type": "boolean"
                    },
                    "useSymbol":
                    {
                        "type": "boolean"
                    },
                    "useDigit":
                    {
                        "type": "boolean"
                    }

                }
            },

            "test1CtrlText":{
                "oneOf": [
                    {
                        "title" : "NO TEXT",
                        "properties": {
                            "useText":
                            {

                            "useText":
                            {
                                "enum": [true]
                            },
                            "textField":
                            {
                                "type": "string"
                            }
                        },
                        "required": ["textField"]
                    }
                ]
            },

            "test1CtrlSymbol":{
                "oneOf": [
                    {
                        "title" : "NO SYMBOL",
                        "properties": {

                            }
                        }

                            "useSymbol":

                                "enum": [true]
                            },
                            "symbolField":
                            {
                                "type": "string"
                            }
                        },
                        "required": ["symbolField"]
                    }
                ]
            },

            "test1CtrlDigit":{
                "oneOf": [
                    {
                        "title" : "NO Digit",
                        "properties": {
                            "useDigit":
                            {
                                "enum": [false]
                            }
                        }
                    },

                            "useDigit":
                            {
                                "enum": [true]
                            },
                            "digitField":
                            {
                                "type": "string"
                            }
                        },
                        "required": ["digitField"]
                    }
                ]
            },

            "test1All": {
                "allOf": [
                    {"$ref" : "#/components/schemas/test1"},
                    {"$ref" : "#/components/schemas/test1CtrlText"},
                    {"$ref" : "#/components/schemas/test1CtrlSymbol"},
                    {"$ref" : "#/components/schemas/test1CtrlDigit"}
                ]
            }

When I use now in my response body:

    "$ref": "#/components/schemas/test1All"

The whole thing is rendered wrong as you see in the image:

There should be three anyOf blocks, but only one is rendered.

When I replace the the 3 last references (test1CtrlText, test1CtrlSymbol, test1CtrlDigit) against the
code of their schemas:

 "allOf": [
    {"$ref" : "#/components/schemas/test1"},
    {
        "oneOf": [
            {
                "title" : "NO TEXT",
                "properties": {
                    "useText":
                    {
                        "enum": [false]
                    }
                }
            },
            {
                "title" : "TEXT",
                "properties": {
                    "useText":
                    {
                        "enum": [true]
                    },
                    "textField":
                    {
                        "type": "string"
                    }
                },
                "required": ["textField"]
            }
        ]
    },
    {...},
    {...}
 ]

I get the following rendering:

Which works as it should, although the label were not rendered:

Start by reproducing the reported OpenAPI schema in Redoc, comparing the dereferenced $ref form with the inline allOf form. Trace how nested allOf and oneOf schemas are rendered; done means all three oneOf blocks appear correctly, with titles handled consistently.
