Details

If you hover a "Styles" marker in the Marker Chart on a performance profile like e.g. https://perfht.ml/2Db2MOb (from bug 1505944), you can see that we report "Elements Traversed" and "Elements Styled".

We don't report anything like that for the Reflow markers right now, but it'd probably be handy if we did.  To start, we could just report the number of "Frames reflowed" (or however we want to phrase it), and report the delta in the count that we added in bug 1115691.
