The thing that annoyed me about this scene was (besides missing this excellent opportunity) that she was out there for way too long without air and already started freezing over, not to mention that the sudden decompression of her lungs would usually also have caused major damage to her lungs. Very much like with the bomber scene, this was just piss poor execution on the part of the set designer and/or screen writer. If they hadn't completely forgotten about force fields, had given her a less silly pose and something like a force-bubble, this would be way less silly, since everyone and their grandmother was already expecting her to show some force stuff.

According to some sources Johnson started writing the script for TLJ while TFA wasn't even done with post production, let alone him having seen it. Apparently he didn't deem it important enough to rectify some things later. That both of them didn't talk with one another might be due to lucas films hire&fire tactics.. but that is just speculation on my part.
