As an aside, if we implemented 'user-select' instead of '-moz-user-select', the linked example would not have this issue, since we don't include non-selectable text in the selection. That said, the example doesn't actually require this, since it moves the 'hidden' text offscreen. We can't really use a warning though since there are valid reasons one might move content around or make it unselectable.
