> There is a very minor bug here that's also present in the master branch. If the size of a window is changed when it's iconified it can't be un-iconified. This notification tells the Java Window that it has been restored even though it's still iconified which confuses the bookkeeping.

That would require adding a call to query the OS for the window's state so we can compare it with the state the Java Window is tracking.

Good catch. I've fixed it.
