/// Note that for performance reasons, we don't call it in the contructor. Instead, we wait for the popup to be opening.
/// The native UIDatePicker contained in the TimePickerSelector is known for being slow in general (https://bugzilla.xamarin.com/show_bug.cgi?id=49469).
/// Using this strategy means that a page containing a TimePicker will no longer be slowed down by this initialization during the page creation.
/// Instead, you'll see the delay when opening the TimePickerFlyout for the first time.
/// This is most notable on pages containing multiple TimePicker controls.
