Accessibility Issue

This is not a major bug but it appears as though the twitter block module is using aria-polite for politeness rather than aria-live, in order to fix this on our site we did the following substitution, but I thought it may be of use to others creating accessible sites:

twitter_block.module:437
-- $block['content']['#options']['attributes']['aria-polite'] = $data['polite'];
++ $block['content']['#options']['attributes']['aria-live'] = $data['polite'];
