Billing block does not autofill while submitting Credit card in Backoffice
It appears that Billing block gets auto filled in when submit credit card contribution from Contacts profile link. 
But if menu link for "New Contribution" is selected then "submit Credit card Contribution", contact billing block does not get auto filled although Billing address is present in the profile.
Not sure if this would be considered as bug!! Thanks.
