Wpf Browser Control Showing Bootstrap.js Error upon Navigation

I have a website that uses bootstrap and I am accessing the website through a wpf form using the web browser control.

When I navigate to certain pages I get a script error window that says Invalid operand to instanceof: Function expected

The WPF form is my way of recreating a client's application where this same issue is occurring.

I can only change the html of the site , has anyone experienced this and found a solution ?

Is there a way to turn on debugging so i step thru and find what is calling the code

Im not looking forward to debugging bootstrap LOL.
