The core fix — split_long_docstring_lines previously split on "\n" only. The fix normalizes all line-ending variants before splitting:

Before:

lines: list[str] = docstring.split("\n")
                                                                                                                                                                               
After:                                                                                                                                                                         
                                                                                                                                                                               
lines: list[str] = (                                                                                                                                                           
    docstring.replace("\r\n", "\n").replace("\r", "\n").split("\n")
