After updating Google Chrome, the report jsPDF in a new Window does not work any more.
The console shows the message:
Not allowed to navigate
Apparently Google Chrome has removed support for top-frame navigation, you can see more informations here: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GbVcuwg_QjM
You may try to render the jsPDF to an iFrame
