This is a problem to a degree even in Messages.app. If a message consists of only a phone number for example, it's very hard to hit the pixel you need to long-press to copy it, otherwise all you get is phone number context like whether you want to call the number, create a contact, or add to a contact. If you manage to hit the frame of the bubble you can get the context menu for copying all of it, but that's often quite hard in my experience.
