This was an API in the WebView Legacy.
Applications like Tumult Hype [https://tumult.com/hype/] allow users to author content, which may inherently want a transparent background. While the editor itself will probably use an opaque window, an export flow may want to export via -takeSnapshotWithConfiguration and use a transparent WKWebView to render into.
Right now, the only way to get a transparent WKWebView is something like:
if(@available(macOS 10.13, *)) {
[webView setValue:@NO forKey:@"drawsBackground"];
} else {
[webView setValue:@YES forKey:@"drawsTransparentBackground"];
}
I am surprised WebView was deprecated without providing this.
