This has been possible ever since AJAX appeared. Everyone should always assume it's happening.
Similar in concept to capturing passwords that don't succeed, in case they may be valid for other sites where the user has accounts.
(Note, I don't do either of these things, just saying that people should not be surprised.)

There are lots of pre-AJAX ways to send data to a server from JavaScript, including requesting Images (which is what Google Analytics uses) and generating dynamic iframes.
