Why enumerated list in reStructuredText docstring doesn't work?

My Docstring format is set to reStructuredText.

Two docstring lines starting with `-` are rendered in the Documentation window as bullet list as expected.

Two lines starting with `#.` or `1.` are rendered as normal lines, without `1.` or `#.`.

The fact that the number is stripped makes me think that it is recognized and interpreted for some reason. 

Is PyCharm interpreting the number in the wrong way or am I doing something wrong?
