Issue : Owner of the workitem changes when creating a child workitem to it in the Plan view.

Hello Team,

We have a Story workitem listed in the Plan View.
Story is in new state and Owned by "A"
In the plan view, try to create a child task, assign it to owner "B".
Move the task to "In Progress".
Story's Owner is now changed to "B".

How can this happen ? Is this the actual behaviour of the workitems in the plan view.
However same doesnt happen, when the workitems are created in the normal view.

Please suggest if this is an issue.

Thanks.
