Description

I'm fairly certain this worked before a recent upgrade. Too busy to check right now. Maybe it shouldn't work and it's just been fixed, but ... I have something like this in a lot of places in my code.

df = pd.DataFrame(np.random.rand(5,3))
df['date'] = ['1-1-1990', '2-1-1990', '3-1-1990', '4-1-1990', '5-1-1990']
pd.DatetimeIndex(df['date'], freq='MS')

Raises about Series not having an attribute inferred_freq. Why is it trying to infer a frequency when I passed freq? Is it a new check?
