1502223 - Timeout Payment Request if updateWith/show promises take too long to resolve

Status: RESOLVED DUPLICATE of bug 1498310

(Core :: DOM: Web Payments, enhancement, P3)

Description

[Matthew N. [:MattN]]

Similar to bug 1447773, if a merchant takes too long to respond to actions we should abort:

A) Slow to resolve a promise passed to .updateWith()
** Demo: https://rsolomakhin.github.io/pr/ko/promise/ is supposed to be a test page for the event promise case but it gives an InvalidStateError so it may be wrong.

B) Slow to resolve a promise passed to .show()
** Demo: https://rsolomakhin.github.io/pr/ko/timeout-show-promise/ for .show(promise)

The UI needs to be notified with `completeStatus: "timeout"` so we can show an error page.

Not sure if we should re-use dom.payments.response.timeout or have a new pref.

Side note: I think the current 5s value of dom.payments.response.timeout should be increased for low-bandwidth users and slow merchant backends. I regularly have transactions take over 5 seconds to process the payment.

I would like to fix this in bug 1498310.
Since these are related to the exception handling about no response from merchant while xxxchange event emitted.
