Interestingly, it’s really not worded much different than fog cloud and no one has any issues with fog cloud.One thing to consider here: If they intended for the spell to work as it had in prior editions, they have an obvious tool to have used that would allow for that interpretation. They'd just have said the area within the magical darkness is heavily obscured (likely with some caveats). They either should have done that had the intention of magical darkness been to block sight through the field of darkness, or they should have been clear that it was not intended to work that way given the history of the spell in prior editions.
It is a poorly worded spell.
