Huh, looks like we missed it in the release notes, but we did add this stop in today's update: "If the opponent controls a permanent that triggers whenever you draw a card AND that permanent entered the battlefield since your last turn, you get priority during your upkeep with an empty stack if you have any legal AND affordable actions."
Note that this will only put the stop automatically on the turn Sheoldred is played. After that it's up to you to put a stop on your upkeep if you want one.
