Worked for me too :)

However, I noticed that there were already cbinds for deleteEmpty for
the mailto/mailto-user fields and wondered why that didn't have an
effect. Turns out, it's because they're nested in another widget and
that requires an additional cbind.

Alternative patch with that approach sent here:
