Help with Chrome v58?

[racitup]

I'm trying to use this on Chrome v58 using a snippet and the console like below, but it doesn't halt even though I know the scope contents is changing. Any ideas?

<run the snippet> -> undefined
bp = breakOn(angular.element(document.customer_form).scope().customer_form.email, '$error');
bp.enable();
<submit the form> -> continues as normal, expecting the browser to halt
