TreeTable/popup window size/layout problem

hello vaadiners

I wanted to create az auto sized window The result was what expected except for chrome I attach some screenshot to demonstrate the problem

so far it seems that the problem is the size of the TreeTable ( context in the picture)

  • if I make the context element setsizeFull(), then I get this huge window
  • if I comment this out 1 get a context which is narrower then the width of the window
  • if I set column expand ratio for the first/only column of the context 1 get a more narrower result then mentioned before

I only want the same result in chrome just as in the other browsers

How can I debug what causes the problem?

Is it a bug of TreeTable or I did something wrong?
