title: Dynamic Fontsize for TextBlock with wrapping
body: <p>I have a TextBlock with a fixed size thats wrapping text. sometimes short sometimes long. </p>
  
  <p>If the text is getting to long it isnt displayed entirely like this</p>
  
  <p><img src="https://i.stack.imgur.com/54ORg.png" alt="enter image description here"></p>
  
  <p>How can i make the Fontsize flexible to make the text fit the TextBox with static size? </p>
