* Electron Version: 2.0.2
* Operating System (Platform and Version): Win10 x64 version 1803
* Last known working Electron version: 1.9.0

**Expected Behavior**
Calling win.setResizable(false) and then win.setResizable(true) should return the window to it's original state. Specifically, it should not change the result of win.isMaximizable().

**Actual behavior**
Calling win.setResizable(false) and then win.setResizable(true) results in the window not being maximizable. The maximize button is disabled and win.isMaximizable returns false.

**To Reproduce**
In any electron application with a window that is resizable, call win.setResizable(false) and then win.setResizable(true). The window will now be impossible to maximize.
