            Bug ID: 239610
           Summary: [model] How can we query availability of <model>
                    reliably?
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Mac (Apple Silicon)
                OS: macOS 12
            Status: NEW
          Severity: Enhancement
          Priority: P2

If the HTML model feature is deactivated, document.createElement("model") neither triggers an exception, nor does it return HTMLUnknownElement like other browsers do.
On all Safari platforms.
What would be a valid way to use Javascript to query this feature reliably? I assume, the standards conform way should be to return HTMLUnknownElement.
