Swapping QR codes in group invites and artillery targeting are latest ploys.

What I find particularly concerning is that the were able to "hide javascript commands that link the victim's phone to a new device" in the payload of a qr-code. I can't see any valid use for javascript in the group joining process, I would expect the code to just be a signal URI with the relevant group ID, so is there sone external javascript interface being exposed?
