Odd behavior with set selection dimensions

[Luke-SF]

I have to have a specific size of image extracted/resized out of a bigger one, and I thought imgAreaSelect would be the natural choice - unfortunately it seems it breaks in this case, as you can see in this jsfiddle:

In general, when maxWidth, maxHeight, minHeight and minWidth are used it seems to not work, or when it does work even just clicking the image appears to break it.
