Reassign Button for Initiator

We just noticed this functionality, where the Reassign button is not available on forms for the initiator, until they re-access the task from their Tasks List.  I can replicate this in a simple model with one user input task chained from the start node, reassign permissions set to 'can reassign to anyone'.  When you start the process from Actions, only the Save button is visible (even for system admins).  If you immediately click Tasks, and load the same task again, from there, the Reassign button appears.

I can't seem to find anything similar on the forum regarding that functionality, and the 19.1 documentation does not note any situations reassign would not appear other than permissions, which are the same in both situations above.

Has anyone else experienced the same issue?

We're currently on Appian 19.1
