pod: swap inputs for filter when invalid default

Browse source 
We usualy want to prefer the filter default value. When this value is
not within the valid range/alternatives, swap the logic and prefer the
defaults of the other pod.

This way we can have a filter with an invalid default that will then use
the preference of the other pod but still enforce some bounds.
