Free-Busy glitches

Steps to reproduce

Everything tried on c.nc.com

1. try to book a appointment with one of your colleague for 1 hour (this is important to chose a meeting longer than 30 min!)

3. After you added a attendee, go to "Find a time"

4. First it looks good, a 1 hour slot is selected:
   

5. Now select a different timeslot

First glitch: Now it only selects a 30 min slot

5. Chose one of the new selected timeslot by clicking on "Done"

Second glitch: The "Find a time" dialog closes but the new selected time is not applied. The event still shows the initial date/time (compare the screenshot from step1 and step5, they are the same)

Start by reproducing the flow on c.nc.com: create a one-hour appointment, add an attendee, open “Find a time,” and select another slot. Compare the selected duration and the event’s resulting date/time; done means a new slot preserves the one-hour duration and is applied after clicking “Done.”
