Click title bar does not refocus a bacground Sub-Window

Hi, I am upgrading a couple of non-trivial Vaadin based applications to Vaadin 7. It is all going quite well but my users keeps complaining about the fact that clicking on a sub-window no longer brings it to the front.
This can easily be demonstrated using the vaddin sampler.

  1. Got to the url: http://demo.vaadin.com/sampler/#ui/structure/window
  2. Click the “Open a new Window” button twice.
  3. Rearrrange the windows so the partially overlap.
    Now if you click the title bar on the background window it does not come to the front.
    However it will come to the frount if you:
  • click somewhere else on the background window
  • drag the window using a click-n-drag on the title bar.
    Does anyone have a quick-fix for this?
    Many thanks, Andrew

Indeed, that’s how it seems like, and that’s definitely a bug. I created a new ticket for it, even though there was a very closely related ticket already opened:
