Here's the answer. I would not see the text. Basically, ng-if is a transcluding directive which means that the entire element is ripped out of the DOM and no other directives are instantiated until ng-if instantiates the Block, but that never happens because ctrl.visible is never even published on the scope, so it's always falsy... chicken and egg problem. Actually, it can be even worse: ctrl could be the parent controller, and if that controller happen to have visible field it can cause unpredictable behavior.
