I also think it makes sense in the situation. Excluding the awkward shot where they just walk past each other, we see Chewie go off to follow Finn and make sure he is okay. It’s just like how Finn helped take care of him earlier in the film. Plus, I think it is in character for him to focus on taking care of someone else to distract himself from the grief. It isn’t until later when things have gotten quiet that we see Chewie by himself, absorbing everything that’s happened.

So, I don’t think it will be really be as distracting if that one shot removes Chewie or is just cropped.

It definitely wasn’t intentional, but it is ironic that JJ forgot about Chewie just like George did in the original story. Though it is a little more noticeable than a missing medal!
