Replication steps:

1. Go to any settings page that has a date selector
2. Click any of the day/month/year drop down, the calendar pops up
3. Click on a date, say 23, 23 does not get selected.
4. Click it again and 23 will get selected now or click any other date it will get selected as well.

Expected result: The clicked date should be selected the first time

Actual result: Two clicks are needed
