add_import adds imports above module docstring when docstring is raw string

[Skylion007]

• I tried to use the add_import functionality like so:
  add_imports = "from __future__ import annotations"

However, it kept destroying my module level docstrings by adding an import before the """ string.
In the project I was working on, we use raw multiline stringsr""" which may be messing with the heuristics to detect module level docstrings here:

isort/isort/parse.py

Line 218 in c6a4196

and not lstripped_line.startswith('"""')

As a temporary workaround, adding the append_only flag has seemed to fix it.

In short, isort will format my code like the following:

from __future__ import annotations
r"""module docstring
"""
from __future__ import annotations

Here is my isort config:

add_imports = "from __future__ import annotations"
# append_only = true # Enabling this is the workaround
profile = 'black'
treat_comments_as_code = "# %%"

Just ran into this very exact problem today. Unfortunately we run isort through gray which does not support passing the append_only config.

Our workaround was to add # isort: dont-add-imports in this file since it already has the import we need.
