Hi Chris,

thanks for the clarification, I thought as much but I was slightly 
misled by the following sentence which talks explicitly about the server 
of the customer:

According to the FSF, since the
Javascript code is delivered from the server of the customer to the web browser
user, it is conveyed, and therefore subject to the terms of the GPLv3

Best regards,
Bart
