On WinRT, you cannot use a custom renderer for the deafult Picker class. The custom renderer is not called unless the custom control is a subclass of Picker. This happens on both desktop and mobile.
### Steps to Reproduce
1. Run the WinPhone or Windows 8.1 project in the attached solution
### Expected Results
The Picker control will have a red background. Run the UWP or Android project to see the expected result.
### Actual Results
The Picker has the default background color
### Testing Info
The issue was reproduced with Forms 2.3
I can still reproduce this with Forms 2.3.3-pre3

I can still reproduce this with Forms 2.3.4-pre2.
- This is only affecting Windows 8.1/WP 8.1 projects. UWP does _not_ have this issue.
- This happens for any registered control that is _not_ subclassed, not just the Picker. I've updated the title accordingly
Subclass the control you want to use a custom renderer for.
