The fix causes all of our failing headful regression tests to pass, so that's good.

We should probably limit activating the window to the case where we are not in an embedded window (i.e., not in JFXPanel or FXCanvas), and where we are a taskbar application. In other words, limit it to the cases where we apply the reactivation workaround on earlier macOS versions.
