Error encountered while attempting to view coverage report

[Dominic Barnes]

I opened zuul in "local" mode and was working on inspecting the coverage report. Once I navigated down to an individual file, the server crashed with the following error:

TypeError: Cannot read property 'text' of undefined

I've reproduced it consistently, you can try it out on my repo:

• clone
• npm install
• npm start
• open the tests in the browser (let them finish)
• navigate through the coverage report (ie: src/ -> index.js)
