This is now just an alias for HyperTextAccessible on all platforms. This was done with the following bash script: ``` cd accessible find -name HyperTextAccessibleWrap.h -delete sed -i 's/#include "HyperTextAccessibleWrap.h"/#include "HyperTextAccessible.h"/;/"HyperTextAccessibleWrap.h",/d;s/HyperTextAccessibleWrap/HyperTextAccessible/g' `git grep -l HyperTextAccessibleWrap` ``` Differential Revision: https://phabricator.services.mozilla.com/D184796
