1. Enter URL for image whose filename contains #.
2. Right-click on image, chose "Save Image As...".
3. Note the suggested filename.

Actual Results:  
The suggested filename is "Zorba#1.jpg.jpg"

Expected Results:  
Suggested the filename "Zorba#1.jpg".

# got truncated.

dup of that bug on using a URI to get the file extension in contentAreaUtils.js
