[v0.47.2+] Non-resizable windows don't fullscreen properly

[TheRealDannyyy]

NWJS Version: v0.47.2+
Operating System: Windows 10
Example Project: JSExecTester.zip

Expected behavior

Non-resizable windows should fullscreen properly as they did before the changes in v0.47.2 were applied. NWjs v0.47.1 and older work as expected for testing this.

Actual behavior

When entering fullscreen with a non-resizable window. The window just ends up on the top-left of the screen.

How to reproduce

1. Download and unzip example project files and run NWjs v0.47.2+
2. Enter document.documentElement.requestFullscreen(); inside the textbox
3. Press the "Run" button and notice wrong fullscreen behavior

@rogerwang could this please be investigated?
I think I narrowed it down to the exact version with the code changes, that probably caused this issue.

If you want to have a window that can't be resized, but can enter and leave fullscreen, use these functions:

function fullscreen () {
  const win = nw.Window.get();
  win.setResizable(true);
  win.enterFullscreen();
  win.setResizable(false);
}
function restore () {
  const win = nw.Window.get();
  win.setResizable(true);
  win.leaveFullscreen();
  win.setResizable(false);
}
