Now you've got two problems...
It is not precisely understood why setTimeout(..., 0) breaks the web if run nested or on next event turn. Arv may be able to supply details from one or a few sites. I suspect the whole problem cannot be understood in any bounded interval, since we're talking not only about the Google-indexable web but also paywalled content, etc.
I'll go with browser-market-share-tested phenomenology (which means "not just Chrome, yet").

Let's go from where we are, based on field testing. Theory is not really helpful.

Why? Given the no-nesting, future-event-turn execution, what invariants are upset by the eval flavor of setTimeout?
