Like the 5% background radiation (or whatever it is) it just doesn't disprove the theory.
What if those photons passing by the sun are affected by the photons coming out of the sun, or by other radiation from the sun, or its magnetic field; or whatever other stuff we have no clue about?

It’s also interesting how the speed of light was determined.
It involved timing of Jupiter’s moons coming around her when Jupiter is on this side of the sun with us as opposed to the timing when Jupiter is opposite the solar system from us.
The difference in the two times is how much longer the light waves took to arrive here when Jupiter was on the other side of the sun.
