What steps will reproduce the problem?
(1) open http://s.codepen.io/stevef/debug/jmWrxV/dXMqBbOKgnPr
(2) check the accessible name value for the 2 text inputs


What is the expected result?
the value of the placeholder and aria-placeholder is exposed via the placeholder property (for example in IA2 a placeholder-text object attribute)

What happens instead?

the value of the placeholder and aria-placeholder is exposed via the acc name property 


Please use labels and text to provide additional information.

mapping for placeholder - https://w3c.github.io/html-aam/#att-placeholder

placeholder maps to aria-placeholder defined here: http://w3c.github.io/aria/core-aam/core-aam.html#ariaPlaceholder

Note: the current implemented mapping was correct at time, but since then placeholder properties have been added to acc APIs to handle the attribute
