Better fix for INC-140
Created by: olafurpg
The previous fix didn't address the root regression from the PR https://github.com/sourcegraph/sourcegraph/pull/40610
The value of occurrences went from undefined to [], causing the if
condition to fail where it used to pass because [] is a truthy value
in JavaScript.
Test plan
See the CI go green. I manually validated that syntax highlighting is still working as expected, and I'm still investigating why the integration tests didn't catch the original regression.
