Xamarin.forms: [UWP] Picker placeholder text
Description
According to the documentation (https://docs.microsoft.com/en-us/dotnet/api/xamarin.forms.picker.title?view=xamarin-forms#Xamarin_Forms_Picker_Title), Title is displayed differently. Actually, it's rendered as a Control.Header on UWP. Is there any specific reason for this? The combobox the Picker is rendered with has a proper PlaceholderText property and it functions flawlessly. Why isn't it used?
It's rather straightforward to work around this issue by creating a descendant of Picker and minimally modifying its renderer but the reason for the original decision simply escapes me.
Steps to Reproduce
- Use a Picker.
- Set its Title.
- Run on UWP.
Basic Information
- Version with issue: current
- Last known good version: none

Is there any specific reason for this?
The Title property seemed to map more naturally to the ComboBox.Header property than the ComboBox.PlaceholderText property. Especially in the case of pre-filled data, where the PlaceHolderText would never be visible to the user, so the purpose of the form field would not be apparent.

Yup.

In a cross-platform world, I want my android and iOS and UWP apps to behave roughly the same without having to make custom renderers for each one to ensure they do.
2 years later, this is still the same and we still have to put in a special renderer to make the UWP app show the text in the placeholder bit just like iOS and Android.
