"Travis CI - Branch Expected — Waiting for status to be reported" despite travis-ci.com enabled for my fork

According to Travis CI - **Branch** Expected — Waiting for status to be reported, for the “Travis CI – Branch” check to fire, I need to enable Travis integration for my fork.

In https://github.com/travis-ci/travis-api/pull/1121, I do have it enabled, and the branch build fires.

But the status check still doesn’t react to it.
