E301: reported incorrectly after ignored E303

[SukiCZ]

Hello, 👋

I have a following code in foo.py:

     1	class FooBar:
     2	
     3	    def foo(self):
     4	        pass
     5	
     6	
     7	    # Comment
     8	
     9	    def bar(self):
    10	        pass

and running pycodestyle --ignore=E303 foo.py (E303 - Too many blank lines) reports foo.py:9:5: E301 expected 1 blank line, found 0 even there is a blank line.

There is one more thing that is confusing me - I'm able to fix this error by adding new line between def bar and pass.

Any idea what could be wrong here?
Thanks

can confirm this is a bug -- seems pycodestyle has been doing this for a while (checked back to 2.4 at least) -- thanks for the report!
