Auto Stripping Tags with Variables?

When the custom block is added, it will strip HTML tags that contains the curly braces. The anchor link will be removed. Only the div will be rendered on the canvas. Is there a way that it will ignore the variables?

blockManager.add('login', {
        label: 'Login Block',
        content:`<div class="forgetpass">
                    <a href="{{forgotpasswordurl}}">{{#str}} forgotten {{/str}}</a>
                </div>`
});
