empty title does not show tooltip

All,

I experimented with SVG tooltips using Firefox, Chrome, Opera and IE 11.
All browsers had similar behavior. All browsers showed tooltips on the
circle when the title contained 'bob'. No browser showed a tooltip when the
title was empty or just had whitespace. Here are the three files I used.

(See attached file: whitespacetitle1.svg)(See attached file:
emptytitle1.svg)(See attached file: arialabel_title1.svg)

                                                              
     Regards,
