This sounds like a case of ‘Handbags’ set to stun.

It is also not exactly new. During the TOS DeForest Kelley (Bones) resented that although he was an established actor appearing in many westerns Shatner had most of the screen time.

According to Carie Fisher Mark Hamill resents Harrison Fords success, but that is just the path to the dark side.

Although it does seem that Shatner can take it all on the chin.
