cell-var-from-loop false positive for keyword-only arguments

# pylint: disable=missing-docstring,invalid-name
for i in range(5):
    def f(*, _i=i):
        print(_i)
    f()
    def g(_i=i):
        print(_i)
    g()

Pylint output

************* Module pylint_repro
pylint_repro.py:3:16: W0640: Cell variable i defined in loop (cell-var-from-loop)

Expected behavior

I would expect the cell-var-from-loop not to be triggered because the value is bound to a keyword argument. The message is only triggered in the presence of the * that forces all following arguments to be keyword-only, i.e. it is triggered for f but not for g.
