Proposal: Rendered / Loaded event for Person control

Description

Since many controls load data in the background it's not obvious from the outside when a control has completed loading / rendering it's content. So an event on controls like the Person control would be helpful that indicates the control has finished updating.

Rationale

For my usecase, I need to know the longest name (and therefore max width) in a list of multiple Person controls since I need to adjust the width of some static layout that needs a fixed px width. Currently I need to get the width after a timeout and hope all users have been loaded.

Preferred Solution

An event like loaded would be great.
