Type: Bug
Behaviour
It is confused by standalone triple quotes as beginning a docstring comment.
Steps to reproduce:
- Open a new tab with this snippet:
def foo():
"""
Sample function that does nothing.
"""
return f"""
This is a {foo.__name__} multi-line string that is returned by
the function.
"""
def bar():
"""
Wrong highlighting ends on the opening triple quotes of the docstring
of this function.
"""
return ""
