Safari DS Select Fix
Workaround for Safari multi-select box bug in DS editor
Description
This extension fixes a minor bug in Safari, where items in a multi-select select box disappear if they are filtered via JavaScript. Occurs only on the datasource editor page as far as I know.
To fix this behaviour, it triggers Safari to repaint the select box by attempting to remove the non-existent 'size' attribute from the select box element.
From what I remember, this bug appears in Safari version 4 and up, including the current latest version 5.1 Oct 2011.
