title: How to set subwindow height dynamically in Vaadin
body: <p>I have a very strange problem in my vaadin application. I am opening a subwindow from main window and that subwindow performs some actions in background and display some new content the process continues to change the contents likewise. </p>
  
  <p>The problem is each content is of different amount so the height of each should be set accordingly. How do I set height of windows? Auto-height isn't working. </p>
  
  <p>PS: I am not using new windows each time instead the content is modified.</p>
  
  <p>Edit: Also custom css like </p>
  
  <p><code>Height: auto; overflow: auto</code> </p>
  
  <p>is not working.</p>
