Bug 166703 – AX: aria-hidden="true" is ignored with aria-flowto

• Component: Accessibility
• Status: NEW

[Jonathan Deutsch]

If aria-hidden=true is on an element, it will still be navigated to by aria-flowto.

Example HTML:

<div id="item1" role="img"    aria-flowto="item2">  Item 1 (role=img, flowto=item2)</div>
<div id="item2" role="button" aria-flowto="item3">  Item 2 (role=button, flowto=item3)</div>
<div id="item3" role="img"    aria-flowto="item4" aria-hidden="true">  Item 3 (role=img, flowto=item4, aria-hidden=true)</div>
<div id="item4" role="radio"  aria-flowto="item1">  Item 4 (role=radio, flowto=item1)</div>

In this case, swiping right will still have it go to item 3, despite its aria-hidden status.  If the aria-flowto is not defined, then it will be skipped, such as this example:

<div id="item1" role="img">  Item 1 (role=img)</div>
<div id="item2" role="button">  Item 2 (role=button)</div>
<div id="item3" role="img" aria-hidden="true">  Item 3 (role=img, aria-hidden=true)</div>
<div id="item4" role="radio">  Item 4 (role=radio)</div>

I am reproducing on iPad Pro with iOS 10.2.1 via:
1. Enabling VoiceOver
2. Swiping to the right
