<div>
<pre>If there is an aria-flowto chain and one of the elements is set to display:none, it will ignore the subsequent pointers and go by DOM ordering.
Consider the following HTML:
<div id="item1" role="img", aria-flowto="item2"> Item 1 (role=img, flowto=item2)</div>
<div id="item2" role="button" aria-flowto="item5"> Item 2 (role=button, flowto=item5)</div>
<div id="item3" role="img" aria-flowto="item6"> Item 3 (role=img, flowto=item6)</div>
<div id="item4" role="img" aria-flowto="item3"> Item 4 (role=img, flowto=item3)</div>
<div id="item5" role="img" aria-flowto="item4" style="display:none"> Item 5 (role=img, flowto=item4, display:none)</div>
<div id="item6" role="radio"> Item 6 (role=radio)</div>
The flowto order would be:
1, 2, 5, 4, 3, 6
However, because item5 has display:none, the actual ordering is:
1, 2, 3, 6
This ordering misses 4, which clearly was meant to be visited. I would have expected aria-flowto to be considered, and simply jump ahead to the next element so it would look like:
1, 2, 4, 3, 6
This means developers need to be very careful when setting display:none, and tools like Tumult Hype need to take extra care in managing flowto chains.
Interestingly this is different than if aria-hidden=true were on the element (see <a class="bz_bug_link
