All is_RealIntervalField
does is
return isinstance(x, RealIntervalField_class)
So I think a better check would be
if isinstance(x.parent(), (RealIntervalField_class, RealBallField)):
Also, could you make the statement :trac:`20069`::
a little more verbose? Something like
Check that this works for arb elements (:trac:`20069`)::
