I noted the bugs, this thread, and the document in the HTML accessibility wiki where I am trying to collate stuff about focus navigation and similar keyboard access issues (in what might yet be a vain attempt to really improve the situation which is overall pretty dismal still): https://www.w3.org/WAI/PF/HTML/wiki/Keyboard

[Shadow]: Shadow host with tabindex=-1, all descendent tree should be ignored for tab navigation
I am not sure if this really is a problem (which might just be my brain going slowly). See my comment for more details, but it isn't clear to me that this needs to be fixed. On further reflection, I wonder if the point is where the author has explicitly marked tabindex="-1" - and how this relates to comound ARIA controls...
Focus on shadow host should slide to its inner focusable node
