Description Caleb Williams 2020-10-28 09:53:06 PDT 
Attaching a shadow root with `delegatesFocus: true` will break a page of a click occurs inside the shadow DOM. A simple reproduction can be found a https://codepen.io/pen/MWeQaME

Update: This seems to happen only when there is no to focusable child in the shadow root (including buttons due to how WebKit handles button focus). With something like an input in the shadow root, things work just fine.

Thanks for filing, I can reproduce this on Safari 14.0 but I haven't been able to reproduce it on Safari 14.0.1 or 14.1. Are you able to reproduce this on later builds?
