Entity Framework Object Context in ASP.NET Session object?

We have a multi-layered Asp.NET Web Forms application. The data layer has a class called DataAccess which impements IDisposable and has an instance of our Entity Framework Object Context as a private field. The class has a number of public methods returning various collections of Entities and will dispose its Object Context when it is disposed.

ASP.NET in Chrome getting a strange focus_change nikkomsgchannel error

Very recently I started to get some strange focus_change errors show up in the console window in Chrome when navigating through my ASP.NET web application (details below). I can’t find anything on the internet that references a “nikkomsgchannel” and have no idea why my application is making a request to this external resource (it never used to!?). Does anyone have any ideas?
