[Bug] Incorrect branches hits coverage statistic

[storenth]

When nyc report --reporter=html done, I try to look at the ./coverage/index.html and found a great defect in Branch coverage number, it always 100%. To validate this issue I suggest clone this simple repo for local reproduce.

thanks for the bug report; I'd be curious if this might be fixed by updating some of the dependencies of puppeteer-to-istanbul, or potentially once a newer version of v8 is released with Chrome (we've been doing a bunch of work around branch coverage).

Need to piece together puppeteer/puppeteer#3712
