Docstring not shown on hover for patched methods

[arjobsen]

Spyder always shows the docstring for objects on mouse hover. This works for classes and methods of classes and also for functions. But apparently not when functions are monkey patched to classes. Although printing the docstring of the patched function prints the docstring just as usual.

Example

class A:
    """Docstring of class A"""

    def method(self, x):
        """Docstring of method of class A"""
        pass

def patch(self, x):
    """Docstring of patch"""
    pass
        
A.patch = patch
a = A()

print(A.__doc__)            # Prints: Docstring of class A              Shows on hover
print(A.method.__doc__)     # Prints: Docstring of method of class A    Shows on hover
print(A.patch.__doc__)      # Prints: Docstring of patch                Does not show on hover
print(a.__doc__)            # Prints: Docstring of class                Shows on hover
print(a.method.__doc__)     # Prints: Docstring of method of class A    Shows on hover
print(a.patch.__doc__)      # Prints: Docstring of patch                Does not show on hover

Expected behavior is that the docstring of the patch is also being shown on mouse hover.
