[Plugin: Trackable Social Share Icons] Adding escape characters to javascript

I’m attempting to add custom javascript functionaliy for the print icon. In the custom button field of the admin panel, I enter the follow code:

print.png | javascript:window.open(“%url%”);window.print(); | 800×1000

On saving changes, trackable social share icons automatically inserts escape characters before the quotation marks. On saving, the code is changed to:

print.png | javascript:window.open(\”%url%\”);window.print(); | 800×1000

On saving again:

print.png | javascript:window.open(\\\”%url%\\\”);window.print(); | 800×1000

And again:

print.png | javascript:window.open(\\\\\\\”%url%\\\\\\\”);window.print(); | 800×1000

This both causes the window.open functionality to not work, and will lead to some very lengthy code after a few more saves. Does anyone know how I can stop this behaviour…and perhaps TSSI, you should file this as a bug ??
