[jQuery] $(this).select(); is funky in Safari?

[chriscoyier]

My goal is to have a text area that has text content in it already,
but when you click into it the text highlights so you can easily
replace it.

$("textarea").focus(function(){ $(this).select(); });

Works great in Firefox (3), but in Safari (dev 4), the text
hightlights quick and then un-highlights.

See example page:

Any hope?
