Note: It's not possible to resize a window or tab that wasn't created by window.open(). It's also not possible to resize when the window has multiple tabs.

Note: This function might not resize the window synchronously. In some environments (like mobile) it might not resize the window at all. You can listen to the resize event to see if/when the window got resized.
