Not sure if it will help you or not, but as far as I know the android application should provide handling of opening and closing window requests from javascript. I mean it does work out of the box, but very often not how it is expected/needed.

It is possible to show separate web window as a dialog, but as I know dialogs can't stack and appear on top of each other. Such approach fits case when you need to open (and then close) only one separate window. Please read more about dialogs here.

What I suggest is to show separate WebView on every window.open() request. Please take a look at this answer, where similar solution was solved. In your case (where any amount of opened windows possible) you can use a LinkedList of WebViews, pushing new one on window.open() and popping top ones on window.close.
