openapi.component needlessly inspects properties, gets stuck

import dataclasses

from sanic_ext.extensions.openapi import openapi

@dataclasses.dataclass

    x: [float]
    y: [float]

    @property
    def reversed(self) -> "Path":  # Recurses
        return Path(

RecursionError: maximum recursion depth exceeded while calling a Python object

This is failing due to:

#openapi/types.py

        return cls(
            {
                k: Schema.make(v, **extra.get(k, {}))
                for k, v in _properties(value).items()          # Does not need to inspect properties for dataclass or Pydantic objects
            },
            **kwargs,
        )

It similarly fails without recursion:

import dataclasses
from typing import Tuple, List
from sanic_ext.extensions.openapi import openapi

@dataclasses.dataclass
class Path:
    x: [float]
    y: [float]

    @property
    def points(self) -> List[Tuple[float, float]]:
        pass

openapi.component(Path)

...

Traceback (most recent call last):

    raise TypeError('{!r} is not a module, class, method, '
TypeError: typing.Tuple[float, float] is not a module, class, method, or function.

There's really no need for sanic to inspect property return types to discover model attributes. Dataclasses, Pydantic or type annotations on the class constructor all provide what is needed.

In the following, the "something" property is added to the schema, for both classes (this is a mistake, I think).
