Description James Craig 2013-04-12 14:44:08 PDT 
ARIA computation algorithm says to always fallback to the host language "tooltip" attribute (WebKit does not use @title as the label on IMG), but I think an explicitly empty alt attribute should override that on img. I've added a test case.

2. D. "The last resort is to use text from a tooltip attribute (such as the title attribute in HTML). This is used only if nothing else, including subtree content, has provided results."
