Did we lose the ability to hide the window frame at runtime on exported apps with nwjs?

I'm trying to request fullscreen with both the brownser and nwjs plugin at start of the layout but I can't get to "true" fullscreen, the window frame is always there.

I looked up nwjs docs about the packages.json file options and fullscreen works fine if I set the "fullscreen" property there to true, but as soon as I exit fullscreen and enter it again through the nwjs/brownser actions the windrow frame is there again.

Am I missing something or did we lost the ability to set fullscreen?

I'm on NWJs 0.46.1 and C3 r197-2
