The difference is if you resize with it off, it stretches the content. If you add it back, the content is kept the same size, and the viewport crops it instead.

The reason these do this is because we're changing the container's height, and the image inside is a percentage. If we change the height of the parent while the child is a percentage, the child also resizes. So I force the size of all the contents to be pixels while dragging. Jquery resize already does this on the on container, but everything inside of it need to be locked down into pixels too.
