Also save your patches of Tab to setWindow.js file.
With this test the detached window emits events, but earlier today while playing with code I’ve got in a situation where it didn’t. I guess becouse of an error right after .detatch call.
setWindow() behaves as described earlier, and there is an error in the console after detatch().
You can filter console output by “~” and follow events…
).
