I think GP mistakenly believes that Chrome implemented this in its proprietary part instead of getting it from Chromium which was the actual case. In reality I think the feature appeared in both browsers at roughly the same time as a result.

And also that they believe that adding features like this to browsers is bad behavior in the first place. If that were the case and people abided by the "do nothing until the W3C acts" rule we'd probably all be using IE6-level browsers still.
