# type: ignore leads to AssertionError

[ZdenekM]

If the following code:

class foo:
    def bar(self):  # whatever comment 
        pass
    bar.__baz__ = None  # type: ignore

is passed to horast.parse, an AssertionError is raised:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/zdenal/.local/lib/python3.6/site-packages/horast/parser.py", line 19, in parse
    tree = insert_comment_tokens(code, tree, comment_tokens)
  File "/home/zdenal/.local/lib/python3.6/site-packages/horast/ast_comments.py", line 27, in insert_comment_tokens
    path_to_anchor, before_anchor = find_in_ast(code, tree, nodes, scope)

    scopes = get_ast_node_scopes(code, nodes)

    assert len(ast_nodes) == len(nodes), (len(ast_nodes), len(nodes))
AssertionError: (12, 13)

If I replace # type: ignore by normal comment, it works. Also, if # whatever comment is removed, it works. Tested with horast version 0.3.1. Any ideas? Many thanks!
