position in jQuery 3.3.1

position in jQuery 3.3.1

Just upgraded from 3.2.1 to 3.3.1 and now some positioning of something I was doing before is off....

I have an image that I am getting the position of:

var position = img.position();

position.left in 3.2.1 is 1379
position.left in 3.3.1 is 1

For some reason I can't get to the blog.jquery.com to see the release notes to see if it is something that is changed or if it is some kind of bug....
