Whilst I admit that is a far better design/safety feature, there still has
to be a reason why the chain came off, and misaligned sprocket/bar is the
most likely cause IMO. Or maybe the sprocket has excessive "wobble" due to
poor construction.

Dunno. I'll take it back and get a replacement. If it does it then I'll
return it for a refund and get one of the others which do have a better
designed front sprocket.

And if Bunnings decides to play hardball I'll then go and chat to CAV.
Hopefully it won't come to that.
