When rescheduling an event with the help of the rescheduling dialogue, the "Pick Date" button in the "Visual Search" tab does not work as expected.

Reproducible: Always

Steps to Reproduce:
1. Create an appointment with attendees where at least one attendee has a conflict so that the "Reschedule" button is active.
2. Click on "Reschedule"
3. Choose "Visual Search".
4. There is no obvious way to reschedule the meeting in this tab, so click on the "Pick Date" button.
Actual Results:  
- Clicking on the "Pick Date" button seemingly does nothing.
- Switch back to "Automatic Search" button: A new date entry called "Move your appointment" has been added to this tab (it was not there before clicking "Pick Date" in the other tab).
- Switch back to "Visual Search" tab: The date entry stays active and it is now possible to proberly reschedule the event.

Expected Results:  
"Pick Date" should enable the "Move your appointment" date entry within the "Visual Search" tab without having to switch to the "Automatic search" tab.
