• Is there a bug report for this issue? I am not sure why or in which environment(s) the current code doesn't work.
• Don't update the bundle, update the relevant source file (most of them are in lib, I think some browser-specific stuff is in browser-entry.js).

It is the problem with the reporter page,while my tests are all pass ,so when I click the 'failures' button to filter the result ,they all hidden, it`s right. But when I click the 'passes' button ,only some of them are shown.

see this https://zerobinbin.github.io/mocha-test-report/runner.html

And Im sorry to update the bundle ，because its my first time to pull a request ,I did it in hurry
