[severity:It bothers me. A fix would be nice]
When a project UI includes a Picker the list should default to the top of the list when opened. This is the case on the Android platform but in Wndows the list defaults to the middle of the list.
Typically the list is created so the most popular items are at the top of the list. In the case of the Windows UI most users will need to scroll to the top of the list.
The default start position should be consistent across all platforms.

Start by reproducing the Picker behavior on Windows with a list whose most popular items are first, then compare it with Android, as described in the issue. The work is done when opening the Windows Picker consistently starts at the beginning of the list rather than the middle.
