Coverage HTML report colors don't make sense

Can you help me understand why the colors/counts in the margin are accurate, but the covered code lines still appear red? Hovering my mouse over a covered line makes a tooltip reading "statement not covered" appear.


PS I have posted this as a StackOverflow question as well, in case you want to answer it there: http://stackoverflow.com/questions/35806728/why-does-my-coverage-report-show-covered-lines-in-red

Start by reproducing the coverage HTML report described in the issue and compare the margin colors/counts with the covered-line styling and tooltip. Done means covered lines are not shown in red and their tooltip no longer says "statement not covered".
