I have the following button, which i would like to be ignored when using the tab key: <button cButton color="light" (click)="..." tabindex="-1">...</button> The tabindex attribute is removed when rendered for html. Without the cButton directive, this does not happen. I can fix this, by using an <a> with cButton. The tabindex is not removed. But I prefere using the button element and hope you can fix this.
