Can you paste the links you found?

The spec change caused rp to auto-close rtc, so the this bug is. But even
before the new spec, rp used to auto-close rt, so I created a test at
http://jsbin.com/bitohe that has:
  <ruby>base<rt><rp>(</rp>ruby<rp>)</rp></rt></ruby>
and it does not render as ruby on Chrome, Safari, nor IE.

After looking at this test results, I started to wonder, maybe this isn't as
critical as I originally thought.
