Currently when regex is used and the InputValue is bound and the control is focused several placeholders are added. This is incorrect behavior. The placeholders should not be added at all in regex scenarios.

===========
Workaround: Set Placeholder property to "" (empty string)

MaskedInput: [iOS] Transparent BorderStyle is not applied correctly.

Implement a Keyboard property which will allow users to set the virtual keyboard according to the expected input

As a workaround, the InputValue could be set at a later stage according to the concrete scenario.

Available in R2 2018 SP release.

The Xamarin.Forms MaskedInput control running on Android with the SwiftKey keyboard app installed does not allow for correct text entry and causes the app to Crash. Using the default keyboard the control works correctly. 

We can consider exposing TextAlignment property that should also affect the Watermark.
