CalendarDatePicker - Cannot Dynamically Change PlaceholderText property once initially set.

[johnt-star]

Describe the bug

After initially setting the PlaceholderText property, setting the property to another value

Steps to reproduce the bug

1. Set the PlaceholderText property of a CalendarDatePicker to an initial value.
2. Dynamically change the PlaceholderText property.

Issue - the PlaceholderText is still the initial value instead of the new value.

Expected behavior

You should be able to dynamically change the PlaceholderText value.

Screenshots

Initial Property Value

The initial PlaceholderText property value is "PlaceholderText".

As you click the "Change Text" button, a counter is appended to the property.

A TextBlock shows the new property, but the PlaceholderText property remains the same

After several button clicks:
