Test cases shy below the IDE area

When attempting the 2024 Fall Challenge, the area for test cases appears empty.
Fact is, the test case list renders below the IDE area.

Perhaps in relation, the following error appears in the browser console:

Possibly unhandled rejection: undefined

(undefined) angular.js:15697:40

`Angular` (9)
