XAML/WinRT/Metro App Q n’ A: How to set border to TextBlock height and width?

Answered this question on Stackoverflow recently. To let a parent element of a textblock have the same size and width as the textblock a simple wrap with width and height set to auto wont do it. But why would you want to do such a thing anyway?
Well you might:

1. Want to follow the recommendation to localize your app, which means that the text can differ in size based on the language- and setting a fixed size might cut the text of,- or allow to much space.
2. Want to be able to dynamically change the text and keep (for example) the border snug
3. or something else

One way to solve this:
[sourcecode language=“XML”]
//

//
[/sourcecode]

I have tried something similar (bind FontSize to ActualHeight of TextBox) but in Metro/Windows store apps this does not seem to work. 
AcutalHeight reports 0 at the time when the binding is executed. 
Later on ActualHeight (e.g. in GotFocus handler) reports correct values.

I have not yet found a XAML-only solution to bind FontSize to Control.Height.
