I need to check the code, but last I knew we query Blink for the computed values, and then tie it back to the authored styles. My hunch is that we either can’t do it for some reason in this case, or there’s a bug.

Seeing as Safari shows all the computed properties correctly, I’m guessing it was something that was introduced after the Webkit/Blink fork? But weirdly, Firefox is showing the same behaviour as Chrome. adactio.com/notes/17236
