Bindable Height of RowDefinition

Hi!

Just want to clarify, is the Height property of RowDefinition supposed to be bindable or not? The documentation* states that it is a bindable property. I tried with the XAML below where TopRowHeight tested as int, float, double and GridLength. The getter is never called.
