title: Angular 12 Data path "" must NOT have additional properties (styleext)
body: <p>What is wrong with the new version of Angular? Angular CLI 12.0.1 can't create new application. Tried to run <code>ng new twelveApp</code> and the cli complains dying <strong>Data path &quot;&quot; must NOT have additional properties (styleext)</strong>.</p>
  <p>I have tried to set the ng-new schema additionalProperties to true but the error remains.</p>
  <p>How to get rid of this additional property?</p>
  <p>PS: back to @angular/cli@11.0.5  everything works quite perfectly.</p>
