Double click on Safari on mac?

Double click doesn't work as expected, can't select word with double click in textarea. In some cases it is possible to select word but response is little bit slow and sometimes it isn't possible at all. Any help for this? Also on Safari on Win works fine, also on other browsers work fine.

Start by reproducing the double-click behavior in the textarea on Safari for Mac, then compare it with Safari on Windows and other browsers. Trace the textarea selection handling in the jQuery highlighttextarea implementation; done means double-click reliably selects a word without the reported delay or failure.
