type hints in methods using PEP 604 result in horizontal line

[cybercyber123]

Bug description

The following type hints cause unwanted horizontal lines, because of un-escaped pipe-symbols.

class FailingClass:
    def __init__(
        self,
        with_default: str | None = None,
    ) -> None:
        self._bar = with_default

    def the_failing_method(
        self,
        the_arg: str | None = None,
    ) -> None:
        pass
