Description Justin Garcia 2009-02-25 18:09:24 PST 
Go to python.org or open the attached WebArchive.
In the fourth paragraph (the one that starts "The Python Software Foundation (PSF) holds...") try and create a selection that starts at the end of the paragraph.  For example, click just after "community." and drag upward.

The selection endpoint is somewhere after "Python conference" instead of after "community."

FWIW, this is not a super-recent regression. Happens on the Safari 4 beta as well.
Comment 4 Justin Garcia 2009-02-26 14:22:45 PST 
I don't know that it is a regression at all.

a better test case

Firefox lets you click on the "clickhere" and puts the cursor inside that text, but if you click below it, then it puts the cursor inside the span that has the large blue bottom border. Not really sure what the preferred behavior is.
