One webview, two displays, both broken

re #44466

• have the snippet below
• invoke the command, you'll have two webviews in column 1 and 2, both are kind of broken

export function activate(context: vscode.ExtensionContext) {

    // Use the console to output diagnostic information (console.log) and errors (console.error)
    // This line of code will only be executed once when your extension is activated
    console.log('Congratulations, your extension "webview" is now active!');

    const webview = vscode.window.createWebview(vscode.Uri.parse('foo:bar/bazz'), vscode.ViewColumn.One, {});
    
    // The command has been defined in the package.json file
    // Now provide the implementation of the command with  registerCommand
    // The commandId parameter must match the command field in package.json
    let disposable = vscode.commands.registerCommand('extension.sayHello', () => {
        // The code you place here will be executed every time your command is executed
        
        webview.title = 'webview';    
        webview.html = '<h1 id="fff">Test</h1><script>document.getElementById("fff").innerHTML += Math.random();</script>';
        webview.show(vscode.ViewColumn.Three);
        // Display a message box to the user
        // vscode.window.showInformationMessage('Hello World!');
    });

    context.subscriptions.push(disposable);
}

Yes the intended design is that a webview should only exist in a single editor group at a time. show should close the editor in column one and move it to the second column. Not doing this currently
