The behavior is the same on Python 3.8.2:

This looks like a defect to me. The "'" *is* being quoted. I.e., there is no syntax error, like this:
>>> 'x'y' File "<stdin>", line 1 'x'y' ^ SyntaxError: invalid syntax
but the quoting character "" is not being removed.

Raw strings aren't quite fully raw, which is why you can't use raw strings for Windows paths:
path = r'somewhere\some\folder\'
doesn't work. The reason is that "raw" (semi-cooked?) strings are s/are/were/ intended for regexes[.]
With all due respect to Steve d'A, I think that reason is inaccurate (at least in MacPorts' Python 3.8.2). I get
>>> path = r'somewhere\some\folder' File "<stdin>", line 1 path = r'somewhere\some\folder' ^ SyntaxError: EOL while scanning string literal
The reason for that, I believe, is that the rightmost "'" is quoted, and there is no "'" terminating the string literal.
Note: I'm just spitballing based on behavior, I haven't looked at the code (sorry, I don't know that code and don't have time to study it).
