coverage/coverage-final.json ignored

[kbirger]

Per the documentation, fragment highlighting only works on coverage-final.json. I have Jest generate this file using the "json" reporter, but it is not working.

lcov.info works, but without fragments (obviously). If I leave the settings on default (check for all 3 types of report), it uses lcov. If I remove lcov, or configure to not look for lcov, I get no highlights, even when coverage-final exists
