The new check looks good to me. I think the only potential issue is in cases where `unextended_sp == sp` and `sp - Interpreter::stackElementSize` is somehow outside of the stack. But, since this is looking at a sender, it would mean that the current frame would definitely be outside of the stack, so I think we're good.

I'll submit tier 1-4 on our CI, and give a check mark when it comes back green.
