Fails to generate for Enum with more than 960 entries

[FlTr]

mkapi aborts generation with "RecursionError: maximum recursion depth exceeded" for an Enum class with about more than 960 enumeration values (narrowed down from originally ~5800 values).

src/my_pkg/my_enum.py:

from enum import Enum, auto

class MyEnum(Enum):
  VALUE_1 = auto()
  VALUE_2 = auto()
  # ... and more ...

> mkdocs build --strict
INFO    -  Cleaning site directory
INFO    -  Building documentation to directory: .<path\to>\_build\docs
WARNING -  MkAPI: api/my_pkg/README.md:RecursionError: maximum recursion depth exceeded
INFO    -  Doc file 'src/my_pkg.md' contains a link '../api/my_pkg/README.md#my_pkg', but the doc 'api/my_pkg/README.md' does not contain an anchor '#my_pkg'.

Aborted with 1 warnings in strict mode!

Excluding this file from docs is acceptable, but using the exclude option does not resolve the issue.

Below traceback appears if there are more than ~970 values.
