Hi, I'm not sure this is related to pytkdocs or mkdocstrings.

Describe the bug
If a footnote is added to one of python objects, the footnote will appear in every object after that one in the same documentation page.

To Reproduce
Here is an example to reproduce

# example.py
def C():
    """This is C
    """
    pass
def B():
    """This is B[^1]

    [^1]: This is footnote
    """
    pass
def A():
    """This is A
    """
    pass

# mkdocs.yml
site_name: Footnote
theme:
  name: "material"
plugins:
  - search
  - mkdocstrings:
      default_handler: python
markdown_extensions:
  - footnotes

Expected behavior
The footnote is supposed to appear only under function B

Screenshots
However, footnote appears under function B and C
