UI doesn't update properly when adding an organizer (but saving does work)

[plehegar]

While trying to add an organizer to an event for the webauthn wg, the UI did not update properly after selecting the individual in the dropdown list. In other words, the individual wasn't appearing after selecting them in the dropdown.

Note that the UI did update properly if I was adding one of the co-chairs for example, so the bug may be related to the fact that the individual I was trying to add wasn't a regular organizer?

In any case, the change was clearly taken into account since saving the change did add the invidual properly.
