Hi all,
at TPAC the provision of a method to draw focus rectangles on a canvas was
discussed, and it appeared that this was considered necessary,
how does this fit in with the use of active-descendent to track focus in a
shadow DOM?

The user scenarios that need to be addressed are:
keyboard only users.
screen magnifier users who use focus highlighting features.
screen magnifier users who rely upon the characteristics of focusable
elements to move focused content into their viewport.

>From the discussions so far in regards to the shadow DOM, it does not sound
as if their will be a relationship between focus on the canvas and elements
in the shadow DOM.
If this is the case then not only will a shadow dom with focus managed via
active descendent have to be created to represent content to the subset of
AT users who do not require the content to be visually rendered , but also
focus management for areas drawn visibly on the canvas, this seems like an
unecessary duplication?
