When I decided to take a stab at something similar, I settled on a different approach in taking an existing asynchronous UI architecture, React Native, instead of just trying to proxy the DOM: https://github.com/vincentriemer/react-native-dom
I think it works better because the original framework wrestles with the same limitations you mention (though an upcoming rearchitecture doesn't), and while it is by no means perfect, some early results are promising: https://rndom-movie-demo.now.sh
