Adding either sortable or draggable to a tabs widget disables the
keyboard functionality. This is easy to see using the example of tabs
with sortable on the jQueryUI site. You can't use the keyboard to
move between tabs and all accessibility is disabled. It's easy to
modify this example to show that the same phenomena occurs for draggable.
I understand that sortable and draggable are not considered
accessible and have no keyboard controls. However, I should be able to
add them to a tabs widget without defeating the keyboard controls that
are there normally. I currently can't add sortable as an option
for sighted users without killing any functionality for screenreader users.
I attempted to post this to the bug database, but it rejected my
post as "spam".
