382270 - The displayed menu item in a collapsed HTML combo box should have SHOWING state exposed via AT-SPI

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Joanmarie Diggs]

Currently, the displayed menu item in a collapsed HTML combo box does not have SHOWING among its states.  While it can be distinguished by the states of FOCUSED and SELECTED, including the SHOWING state would mean that the visible text could be identified in the same fashion as one can do with lists rather than having to be handled as a "special case."

Steps to reproduce:
1. Navigate to https://bugzilla.mozilla.org/enter_bug.cgi?product=Core
2. Use Accerciser to examine the severity combo box.  None of these 
   items have the "showing" state, including the one that is showing.

Notes:

In bug 366340 (https://bugzilla.mozilla.org/show_bug.cgi?id=366340#c14), Nian said:
> if select is collapsed, remove SHOWING state

Had I seen that at the time, I would have protested. :-) If that was indeed included in the HTML combo box a11y cleanup (https://bugzilla.mozilla.org/show_bug.cgi?id=379678), any chance we could have SHOWING back?

Thanks!!

Attachment: Inherit invisible/offscreen from combobox. If combo is neither, then ensure showing option is marked SHOWING
