I'm not an export here but a first looks:
The script interleaves severals call to window.innerWidth/innerHeight/clientWidth/offsetWidth with DOM modificatins. This means that we have to force several sync reflows to answer these queries. Ideally we need to avoid all queries that require a sync reflow.
