Nothing -- until the tank gets too hot.  Then boom.  Actually, it might
also spit liquid into the regulator, which isn't meant for it.

Stays right there.

Nope.  There is no vent on the regulator.  Each stage has an opening to
atmosphere to allow the regulating function to work, but any propane coming
out indicates a diaphragm failure.  To get rid of excess liquid you have to
vent it through the bleed valve.  Beware -- the valve will become very
cold, and if it is moist it will freeze and you will be unable to close it.

The 20% headspace is deemed sufficient for safety in any reasonable
temperature.
