What does the w3c standard say about tabbing away from a disabled element?
I'm looking at the behaviour of Chrome and my test framework and trying to understand what the correct behaviour should be before raising an issue/ticket on one or the other (or revisiting how my test works).
The test/user operation is to tab onto a button, press enter and as a side effect that button with focus becomes disabled. Then the user tabs away from that button to one that's adjacent in the DOM.
There's a working example in a question I asked on StackOverflow here.
What happens in the browser is that the focus switches to the adjacent button.
But in the test, the focus switches back to the first navigable/focusable element inside the disabled element's parent element.
I've looked though various parts of the standard but I'm either missing it (it's quite a dry read!) or that behaviour isn't defined?
What is meant to happen when tabbing away from a disabled element?
