Cannot ignore type errors in multiline strings

stringy = "foo"

f"""\
{stringy.nope()}
"""  # type: ignore

(ignore that this is a true positive - my real code is much more complicated and is actually valid, the above is just a contrived example to show the core problem)

In Python 3.7 with mypy 0.782, it reports the error on the closing """ (if you remove the # type: ignore), so it picks up the ignore directive and all is well. In Python 3.8, it reports the error on the previous line. There's no way to add # type: ignore on that line, and adding it anywhere else has no effect.

In other cases it tends to report the error as being on the line with the opening """… I'm not sure why in this particular, contrived example it behaves differently. But either way, it's a major problem, since there's no practical workaround for this [in my much larger, real-world code]. It's blocking the upgrade to Python 3.8 for one of my major projects.

(the output from mypy w/ Python 3.8)

test.py:4: error: "str" has no attribute "nope"

Reproduziere den Bericht mit dem bereitgestellten test.py-Snippet unter Verwendung von Python 3.8 und mypy 0.782 und vergleiche anschließend die Diagnoseposition mit Python 3.7. Verfolge die Diagnosen für mehrzeilige f-Strings und die Behandlung von # type: ignore; abgeschlossen ist die Aufgabe, wenn das Ignore an der abschließenden dreifach in Anführungszeichen gesetzten Zeichenkette den gemeldeten Fehler konsistent unterdrückt.
