Ionic 1 + ngUpgrade seems to have lots of problems

Has anyone been able to successfully use ngUpgrade with Ionic 1? I’m attempting to do so right now. I can get the app to run but it is very slooooooooooooow.

I’m also seeing a weird issue where, whenever I click on an input, the keyboard opens then immediately closes on its own. So basically the keyboard just flickers.

I’m using Ionic 1.3 and I’ve found that if I go into the ionic-angular.js file and comment out the following code (line 1441 at the time of this posting), then the keyboard issue is fixed:

$rootScope.$on('$ionicView.beforeEnter', function() {
    ionic.keyboard && ionic.keyboard.hide && ionic.keyboard.hide();
