Type hints for custom objects not linked

Expected Behavior

File called 20210409_pdoc.py

class Child:
    def __init__(self, name: str ="child"):
        """
        One child description

        Args:
            name: name of child
        """
        self.name: str = name



class Parent:
    cls_child: Child = Child("name of cls child")

    def __init__(self, child: Child = None):
        """
        Parent object

        Args:
            child: child instance
        """
        self.child: Child = child

Running pdoc3 20210409_pdoc.py --html yields

Ideally, the type hints would be links to the actual class.

Actual Behavior

No links, but instead the filename is printed

Additional info

Start by reproducing the issue with the provided 20210409_pdoc.py example and pdoc3 20210409_pdoc.py --html. Trace how the generated documentation renders the Child annotations, then verify that custom-object type hints link to the documented class instead of displaying the filename.
