macOS WKWebView background transparency

If someone has experience with WKWebView, please share how to make the background of the view transparent. The WebView object has such option via var drawsBackground: Bool { get set } but it is missing for the WKWebView class. I searched the net and .. found nothing. Before time it was possible to do so via opaque property, but not anymore. There is a getter isOpaque ... and that's it. I don't want to do it via CSS and already tried everything else, like:

webview.wantsLayer = true

webview.layer?.backgroundColor = NSColor.clear.cgColor

If someone can help ...

This should work for both macOS 10.11 and macOS 10.12:

if NSAppKitVersion.current.rawValue > 1500 {
    webView.setValue(false, forKey: "drawsBackground")
}
else {
    webView.setValue(true, forKey: "drawsTransparentBackground")
}

Remark: this has been passed by App Store review.

Your web page should have transparent background as well.
