See the test-case and scroll down. You should see a bunch of paragraphs with the same content repeated over and over, but some of them have missing content.

70 seems good, 72 seems bad, 71 is pretty stretched, non-WR is good. I can't run a more detailed regression range atm, but this is the pushlog I got so far: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=0e0e9c22321ed9f284744cfeb3507710b2d5d606&tochange=26711f10f5f45471b5856fb5cef08948f0e5bc21

It contains various suspect blob changes, so ni? Jeff :)

Also, I spotted this in the wild (on polygon.com, fwiw)

Looks like we're not painting some lines of the text into the mask for some reason.
