I think the issue is orthogonal. I'm not a huge fan of react but it's an example of an architecture where the structure that is (imposed/encouraged) helps avoid the problem you're talking about.

I don't think the issue is "markup expressed in another language" - I think it's "poor application architecture". I don't dispute there might be a correlation between libraries and frameworks that do poorly on each - but that doesn't mean it's intrinsic.
