Subject: Flash-based filters are now strrrrrrrict AND accessible!      MDL-7889
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=f6994e71fa4b5c1ccec577f637cf08fe6a532325;p=moodle.git

Unfortunately this is only possible using Javascript to rewrite the DOM, so this means Flash content won't work without Javascript on.
