Fix layout crash & bubble anything with valid bubble metadata intent

I meant to bubble anything with valid bubble metadata intent but in
ag/6004126 however I missed a spot.

Crash was just wrong layout casting; the code is a little awkward
but I'm planning on refactoring it in future CL so it'll be better
just want to not crash sooner :)
