What if the author has set it to something else? Thank you for the great suggestion. I was under an assumption that Shadow DOM needs to enforce encapsulations, but your suggestions brought me two questions I'd want to run with Shadow DOM experts: 1. If Shadow hosts are inline, do we want its bidi state isolated or not from the parent tree? 2. Your suggestion makes sense, but then it'd be author's responsibility to set it correctly for custom elements. Are we ok with this, or do something in custom elements? I don't have answers to these questions right now, I'll look into further. Thank you for your thoughts! /koji
