Hi Chaals,

Thanks for the pointers.

I was not aware that positive tabindex value is being deprecated, but
anyway it should make sense
when tabindex=0 specified on the shadow host. And as it has not been
completely deprecated,
it should be okay to keep the document as is, but I will add some comments
or pointer.

For aria-activedescendant, I was not aware either, do you think it still
make sense when the
real active descendant is in a shadow tree (i.e. the host and the active
element live in different scope)?
(added public-html-a11y to cc)
