Yes, this is normal. I've forgotten what this specific kind of CA is called,

Longitudinal Chromatic Aberration (LoCA).

but it's normal at wide apertures to have one color on sharp edges beyond the plane of focus, and the other color in front of the plane of focus. It should be fairly easy to remove in a program like Lightroom.

Indeed, it is normal to see magenta/red in front of the focus plane and green behind, with a lens like this. Some lenses show blue/yellow LoCA, but that is very rare.

As the length of a thread approaches 150, the probability that someone will make the obvious "it's not the camera, it's the photographer" remark approaches 1.
