Stats become undefined or throws error in new window - IE Edge only

Hi We are using stats to store almost every value of our application
There are some scenario like we need to open a new window and display some contents or
have some click functions which again checks or stores/updates stats values.
But in IE edge (Windows 10) alone we are not able to fetch values from stats
Mostly it throws this.get('stats.user') is undefined or errors like such
But it works well in IE 11 and and chrome
