1987799 - CardSections assumes that `newtabTrainhop` Nimbus feature has `dailyBriefing` defined

Status: RESOLVED DUPLICATE of bug 1987796

(Firefox :: New Tab Page, task)

Description

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

STR:

0. Ensure sections is enabled
1. Follow the instructions in https://phabricator.services.mozilla.com/D264079
2. After the last step, go to about:studies and unenroll from the study
3. Open a new tab

Alternatively, instead of enrolling in dailyBriefing as part of Step 1, set the following value for the newtabTrainhop feature:

{
  "type": "test",
  "payload": {
    "enabled": true,
    "sectionId": "top_stories_section",
    "placement": "section"
  }
}

and then open a new tab. This results in a broken set of story cards (if sections is enabled).

D'oh, Bugzilla hiccup.
