[Question] - support unsupported invokers

[yinonov]

Common practice for custom-elements present a problem where host would fail to be recognized as supported invoker but its template should be.

<div popover id="mypopover"></div>

<my-button popovertoggletarget="mypopover">
  #shadow-root
  <button>

the above will not trigger the popover to show / hide.

follow that, common better practice will be to delegate the attribute downwards to the focused button

<div popover id="mypopover"></div>

<my-button popovertoggletarget="mypopover">
  #shadow-root
  <button popovertoggletarget="mypopover">

but that won't return the popover element as it doesn't exist in the shadowed button root node (where it will be queried)

What about simply aria role="button". should that be supported?

<span role="button">
