Docstring tooltip bullet points not indented correctly if header is present

[bshoshany]

(I'm reusing the duplicate issue I accidentally opened to report a different bug, since I cannot delete the original issue)

Steps to reproduce:

Write the following Python program:

def test():
    """
    #### Header
    * Level 1
        * Level 2
        * Level 2
    """

Hover over the function. The indentation of levels 1 and 2 will be the same.

If you enable our new restructured text support, it should work:

I can confirm that this solution works, thanks!
