win.requestAttention() doesn't work in NW.js 0.50.x

[AshleyScirra]

NWJS Version : reproduces in both 0.50.0 and 0.50.3
Operating System : Windows 10 64-bit

Expected behavior

The window 'requestAttention' method should work.

Actual behavior

It doesn't seem to work in 0.50.x. It logs a console error: Unchecked runtime.lastError: The context from which the function was called did not have an associated app window.

How to reproduce

Minimal repro:
win-requestattention.zip

Click the button. It just runs: nw.Window.get().requestAttention(3);

I am also seeing this behavior with NW.js 0.58.0. This fails in all of the following scenarios:

nw.Window.open('page.html', (newWindow) => {
  newWindow.requestAttention(true);
});

nw.Window.get().requestAttention(true);

nw.Window.get().requestAttention(false);

nw.Window.get().requestAttention(3);

These all fail with the same error @AshleyScirra mentioned:

Unchecked runtime.lastError: The context from which the function was called did not have an associated app window.

@rogerwang I hate to ping you but this sure looks like it'd be an easy fix and has been open for almost a year. Any input?

@rogerwang This is still broken with 0.62.0.
