Module misinterprets a div's data attribute 'data-action' as 'action' and incorrectly alters it's value

It has to do with the regex in line 160 in pathologic.module:
return preg_replace_callback('~(href|src|action|longdesc)="([^"]+)~i', '_pathologic_replace', $text);

Here is the source code that is being misinterpreted:
<div class="fb-like fb_edge_widget_with_comment fb_iframe_widget" data-send="true" data-layout="button_count" data-show_faces="false" data-width="150" data-action="like" data-font="verdana" data-colorscheme="light" fb-xfbml-state="rendered">

What happens is that 'data-action="like"' is replaced with 'data-action="/like"', and the Facebook JS code complains that the action ("/like") is unknown.
