I was curious about the same thing when I saw this headpiece, although the Juggernaut effect does not carry over to it.
Kind of disappointing, but there is a chance it might be patched to work later on. (So I would say just wait to see if it does.)
I remember thinking the same thing about the Grenth helmet, since the non-face part of that mask didn’t chrome initially, but it got patched a few days in to actually get fully affected by the Juggernaut.
Hopefully the tattoo gets patched though.
