Can you confirm if the Flow Designer error "Can't Load Invocable Actions" that is thrown when an instance has Person Account Actions is going to be resolved in Spring'15 production release?

Loading flows in Flow Designer error if org has a quick action defined on Person Account (Reference W-2477447)

Overview of Issue:

If you have Global Actions defined for person accounts, then when the Flow designer is loaded an error is displayed and all actions (Static Actions, Custom Action and Email Alerts) are missing from the Flow designer palette

If the actions are deleted, Flow designer actions are restored.
