IFrame::Update Visibility Synchronously considers visibility: hidden as visible, but Pres Shell::Mark Frames In Subtree Approximately Visible doesn't
See bug 1312770, comment 53. The difference stems from when this code was first landed. I'm not sure if I had a reason for that, but having these two pieces of code disagreeing is not what we want.
