//One possible problem arises when the ngIf is placed on the root element of the template.
//ngIf removes the node and places a comment in it's place. Then it watches over the expression and adds/removes the actual HTML element as necessary.
//The problem seems to be that if it is placed on the root element of the template, then a single comment is what is left from the
//whole template (even if only temporarily), which gets ignored (I am not sure if this is browser-specific behaviour), resulting in an empty template.
