Additional context

Priority

I'm assigning a medium priority because only the WP Nightly tests are failing.

Reason why this e2e test is broken

The tests are failing due to missing elements in the DOM. Given it's only failing for the WP Nightly tests this could be related to some upstream changes in the structure of the DOM (needs to be confirmed). For this reason I'm adding the e2e: broken environment label

Important

Please, ensure when closing this issue (PR fix) that only one e2e: broken label is added and it is accurate.

• I confirmed there's only one e2e: broken label in this issue and it is accurate.

I'm pulling off the priority and routing to the checkout payments focus area so the team can double-check on priority during their triage.
