pinch out in quicklook for video files - no fullscreen anymore?

Hi, I updated to OS X High Sierra a couple of months ago and noticed a considerable improvement to the system, but some features are not available, or I haven't found them.

The one concern is that when I would quicklook a video file and pinched out on it, it went fullscreen. That was a very nice shortcut, now I have to push the button on the upper left to do that.

Am I missing something here, or the feature isn't available to this moment.

I'm using 10.13.3 on a 15inch late 2011 macbook pro.
