One dot is missing for leading ellipsis in doc markdown

[Azureblade3808]

Environment data

• Language Server version: v2022.6.20
• OS and version: Windows 7
• Python version (& distribution if applicable, e.g. Anaconda): 3.8.12 Anaconda

Code Snippet

def annotation(x):
    """
    Example
    -------
    >>> class C:
    ...     @annotation
    ...     def f():
    ...         ...
    """
    return x

Repro Steps

1. Copy and paste the code snippet into a python file.
2. Hover annotation and see its doc.

Expected behavior

The doc markdown is rendered correctly.

Actual behavior

Every leading ellipsis is short of one dot.

Additional Info

1. It seems that a "@" phrase after leading dot(s) is causing this behavior. And a simplified sample would be

def f():
    """
    >>> a
    . @1
    .. 2
    ... 3
    .... 4
    """

2. Wrapping the code as code blocks using ``` doesn't help.

3. As far as I can tell, the same doc(s) can be rendered correctly up to v2021.1.3, but not since v2021.2.1.

I believe this is a result of fixing cv2 doc strings in this commit:
microsoft/pyright@e278f28

I'll look into if we can special case the cv2 instead.
