Unable to get property 'PageManager' of undefined or null reference SP2013

Question

I've just created a new custom list on my site, with a simple list, one text column, no javascript, no CEWP, just a very basic vanilla function.

Running the page with PF12 open, the error "Unable to get property 'PageManager' of undefined or null reference" comes up.

Is this normal? What is causing this? Any fix?

Debugging causes these errors to throw. Do   E in PF12 and select the "Never break on Exceptions" option.

Problem goes away!
