Ask HN: Web app freezes, but not when Chrome is recording. How to debug?

I have a super annoying heisenbug, that never occurs during the Chrome debugger performance recording session. Basically it's an Angular/AngularJS hybrid app with a form that freezes when you return to it after navigating to another tab.

Any suggestions on how to debug this other than just commenting out code step-by-step?

If you can't inspect it due to it freezing, I suggest trying to make it not freeze to begin with.

Slash dependencies and code until you get to a state that doesn't freeze. Then start adding dependencies and code back one at a time until it starts freezing again.

Narrow it down and you'll get it, eventually.
