[Bug] Click Block Does not function, resulting in Black Screen

[curtisblanchette]

Short description of the problem:

Clicking the back button repeatedly can cause the navigation stack to accidentally pop the rootPage off of the DOM. resulting in a black screen.

What behavior are you expecting?

The click block element should function as expected, adding the class of 'click-block-active' when the back button is interacted with. Removing this class once the transition has completed.

I say this is a click-block issue since the back button shouldn't be able to be clicked more than once. It seems like multiple back clicks causes root page to be popped off the stack.

Steps to reproduce:

1. create a new ionic v2 start tabs project
2. create a button on a tab page that transitions to a subpage with a back button
3. add a bunch of images to the subpage so that their is heavy content
4. click the back button as fast as possible before the transition completes

Please note that this is not easily reproduced. You must be patient and hammer on the back button

Notice the root tab page will be removed from the DOM resulting in a black screen.

<ion-tab role="tabpanel" tabicon="information-circle" tabtitle="About" ng-reflect-root="function AboutPage(navCtrl) {
        this.navCtrl = navCtrl;
        this.subPage = SubPage;
    }" ng-reflect-tab-title="About" ng-reflect-tab-icon="information-circle" id="tabpanel-t0-1" aria-labelledby="tab-t0-1" aria-hidden="false" class="show-tab">
   <div></div>
   ** page is missing from here **
   <div class="nav-decor"></div>
</ion-tab>
