> No matter what the first line of the buffer is, if the second line is
> a string literal, `python-info-docstring-p` will misjudge it as a
> docstring.  This issue can be reproduced as follows:
> 
> 1. emacs -Q
> 2. Open a Python file whose contents are as follows:
> 
> #+begin_src python
> import sys
> """Not a docstring."""
> #+end_src
> 
> 3. Locate the point at the string literal on the second line.
> 4. M-: (python-info-docstring-p)
> 
> Although this string literal is not a docstring, it returns t.
> Therefore, in `python-mode` (not `python-ts-mode`), this string
> literal is rendered in `font-lock-doc-face`.
> 
> This is the reason I changed some ERTs to "expected fail" in the
> commit b7b82ecb2b4c2ce33c11e5388b692cd403ab55e6 of Bug#63622.
> 
> Attached is a patch to fix this bug and the above mentioned ERTs and
> to restore ERTs I deleted by mistake in commit
> 6b2c8dc9050c5c0514fa404733ce1d4a37d00e39 of Bug#63844 (related to
> Bug#63622).
