Hi, I have 2 element of <app-root> in dom like this: <app-root ng-version="5.2.9" style=display: none >...</app-root> <app-root ng-version="5.2.9"></app-root> I see i the browser the html but without style. If i remove the second element and change the display to block i see the html fine. what causes the duplicate elemetns???
