My guess is that you have some JS code that offers HTML5 placeholder
support for browsers that don't support it natively. It could work by
managing the value of the input and changing it onfocus, onblur, etc.
If it doesn't have code to properly clear the managed value and remove
the placeholder, that might accidentally get submitted to WordPress.
Or, maybe there is just a browser out there that is improperly
implementing the placeholder feature. It's almost certainly not a
WordPress issue, however.
