Current behavior
Just by including Angular in a SharePoint environment a memory leaks starts to occur in IE11, Edge, for every page reload the memory increases and is never released until the browser is closed.

Expected behavior
No memory leak

Minimal reproduction of the problem with instructions

1. Add a script editor webpart to a SharePoint page
2. Include the angular javascripts
3. Save and publish page
4. Start reloading the page in Internet explorer 11
   You can see that the memory is increasing and it is not released between page loads

What is the motivation / use case for changing the behavior?
Memory Leak = Bad, We have 60+ customers running IE getting memory leak until browser hangs

Please tell us about your environment:
We have a SharePoint Online environment ready where you can get the login information so that you can test the behavior!

• Angular version: 2.3.0

• Browser: IE11, Edge

Can you create a repository that we can clone that demonstrates this?
