The tame foxes if freed would return fairly quickly to being foxy. Humans on the other hand have continuously changed the environment in which they live (for say 50,000 years). Therefore the selective pressure is not static. So it is not surprising that new genes can arise and flow through populations. Dogs are not relevant here.
Arguably while conditions have changed for humans massively in the recent past the same could be said of many domesticated animals or at least dogs (as a fun exercise check out how often the primary used and role of dogs has changed in say Anatolia over recorded history).
And more importantly all this time we humans have basically been self-domesticating ourselves.
