Bug 166670 – AX: Focus should jump into modal dialogs when one appears

• Component: Accessibility
• Status: RESOLVED FIXED

[Nan Wang]

VO should jump to web dialogs/menus if focus isn't moved (within some timeframe) when one appears. 
This should be limited to modal dialogs. (@aria-modal).

do we have to wait .1s here or can this be faster?

Hi, I faced these issues with the current implementation:
1. if dialog has no children, the focus is not moved to the dialog (it has a valid tabindex, -1 or 0)
2. focus is always moved to the first focusable child, w/o respecting the tab order (e.g. 1st focusable child has tabindex=0, 2nd focusable child has tabindex=1)
3. focus is moved in the dialog only by toggling aria-modal attribute from false to true. I'd expect toggling the visibility of the element would trigger the focus move (e.g. display:none -> display:block)
