HTML Reporter Fails with `meta` being undefined #708

Closed bassettsj closed 8 years ago

bassettsj commented 8 years ago

When using babel-plugin-istanbul some of the files are not returning the expected meta for the html reporter to be able to annotate the files correctly. I get the following error for the stack trace.
