Looking some more at PR 41, it's not clear what to do in NewPromiseReactionJob if the handler is empty and the promise capability is not undefined

IIUC this would be the case with something like

const delayedRejection = new Promise((_, reject) => {
  setTimeout(reject, 1000);
}).then();

I think the right snapshot there should be the one from the promise resolution that triggered this reaction, but it's not immediately clear to me how to make that work in the spec

Andreu Botella: Do you have a case in mind where you're not sure what the observable behavior is?

I think if the handler is empty, there isn't really any snapshot propagation that you have to do in the first place
