The SVG Accessibility Task Force had indicated that in the case of SVG, any element with a presentational role should be excluded from the tree -- even if it had global ARIA attributes. See [1]. This behavior was part of the implementation I did [2]. After some subsequent discussion, the Task Force consensus is that this "golden hammer" behavior is not desired and that global ARIA attributes should trump the presentational role. [3]

Patch shall be forthcoming.
