I agree with you. I'm concerned about memory leaks from the circular references,...

Circular references are garbage collected -- no need to worry about them.

You might be thinking of a terrible old IE bug where circular references between JavaScript objects and DOM nodes were never collected, but that's never been an issue with JavaScript-only references.

Oh, I didn't know that. That alleviates many of my concerns, then, thank you.
