So is the electric field. Fuv is not.
The electric field has no more priority than the magnetic field.

I disagree. Within any reference frame or any set of reference frames
that are moving at speed<c with respect to each other, an observer will
observe both electric and magnetic fields in light. It is not necessary
to move to the photon's frame itself to ask what that frame observes
about the photon. (It's not only irrelevant but impossible.)

You'll note that it did nothing to affect the validity of Maxwell's
equations. Maxwell was correct in his math -- the interpretation
changed a bit.

So is electricity.
