Autotester assigns full PyTA marks to code with syntax errors

[hhc97]

Markus setup:

Example code:

    def __contains__(self, item: Any) -> bool:
        """Return whether <item> is in this list.

        Use == to compare items.

        >>> lst = three_items(1, 2, 3)
        >>> 2 in lst                     # Equivalent to lst.__contains__(2)
        True
        >>> 4 in lst
        False
        """
       current = self._first

        while current is not None:

            if current.item == item:

                return True

            current = current.next

        return False

The above code has a syntax error (see indentation of thecurrent = self._first line). When running the code, python returns this error:

  File "prep5.py", line 100
    current = self._first
                         ^
IndentationError: unindent does not match any outer indentation level

However, PyTA returns full marks for this file as seen below:

After speaking with @david-yz-liu, I believe this is not intended behavior.
