Why This Is A Problem\r\nOrphaned windows equate to leaked memory.\r\n\r\nh2. Expected Behavior\r\nTapping the tab's button should close every window that is open on that tab's stack, not just the current window.\r\n\r\nh2. Reproduction\r\nDrop the following in an app.js. Touch \"S1: Touch Me\", then \"S2: Touch Me\". Notice in the log which windows were opened, and which were closed.\r\n{code:title=app.js}\r\nvar tabGroup = Ti.UI.createTabGroup();\r\n\r\nfunction openWindowOnStack(i) {\r\n    var win = Ti.UI.createWindow({\r\n        title: 'I Am ' + i\r\n    });\r\n    win.addEventListener('open', function() {\r\n        Ti.API.info('opened ' + i + '!');\r\n        if (i < 4) {\r\n            openWindowOnStack(i + 1);\r\n        }\r\n    });\r\n    win.addEventListener('close', function() {\r\n        Ti.API.info('closed ' + i + '!');\r\n    });\r\n    tab.open(win);\r\n}\r\n\r\nvar outer = Ti.UI.createWindow({\r\n    title: 'I Am Parent',\r\n    rightNavButton: Ti.UI.createButton({ title: 'S1: Touch Me' })\r\n});\r\nvar tab = Ti.UI.createTab({\r\n    window: outer, title: 'S2: Touch Me'\r\n});\r\ntabGroup.addTab(tab);\r\n\r\nouter.rightNavButton.addEventListener('click', function() {\r\n    openWindowOnStack(0);\r\n});\r\n\r\ntabGroup.open();\r\n{code}\r\n\r\nh2.
