I have a Quicklook appex that show the file contents by a WKWebView. 
The preview inside a normal quicklook window works well, but if the window is in fullscreen is not possibile to scroll with the trackpad gesture.

I do not know is is related to bug [219632](https://bugs.webkit.org/show_bug.cgi?id=219632).
Using the deprecated WebView insted of WKWebView the preview can be scrolled on fullscreen mode.

I have created a demo code here:
