When you open up the sidemenu then close it, a gray square appears in the upper-left corner. Here's a screenshot of the issue:

This issue was reported on #6416 but was closed on Aug 22. Despite multiple comments over the course of two months it's still a problem, the issue remains closed and not looked at.
I'm expecting to not have that gray box there when you toggle the menu. It makes the app look non-native, which hurts the case for Ionic.
Steps to reproduce:
$ ionic start MyIonic2Project tutorial --v2
ionic run android --device.Which Ionic Version? 1.x or 2.x
