Window does not always open/close when icon is clicked

[jdp]

Reproduced with the example app, menubar from git checkout (a6afe2e) on Mac OS X 10.10.5.

The window does not always open or close when the icon in the menu bar is clicked. Sometimes it takes 5 or 6 clicks before the window responds. I also noticed that the icon doesn't stay highlighted when the window is open, where other menu bar apps keep the icon highlighted.

I debugged this a bit and it seems that it is not a problem of menubar but a problem from electronjs itself.

In line 67 of the index.js menubar.windows.isVisible() is called and sometimes it returns true even if the window is not visible and then hideWindow() instead of showWindow() is called.
