Hi Travis, 

It is a UI accessibility requirement (on keyboard supporting platforms) that
scrollable regions be operable (scrollable) using the keyboard. If this is
achieved via making the region focusable by default and included in the default
focus order, then it is a sane move.

Regards

"Draggable" elements are already included in the list in a similar spirit.  IE would be willing to make a change to this behavior if other browser vendors will also make this change.

These specify that scrollable elements are focusable, but not suggested to have their tabindex focus flag set or be tab-accessible.  This would imply that IE's behavior is currently compliant with the spec -- the element is focusable but not reachable by tabbing.

I'd like to see scrollable regions added to the list of suggested elements which have the tabindex focus flag set by default to enable this scenario better.  "Draggable" elements are already included in the list in a similar spirit.  IE would be willing to make a change to this behavior if other browser vendors will also make this change.
