Inherited methods are no longer italics in the right sidebar (regression)

[Hixie]

Contrast the right sidebar in these two:
https://api.flutter.dev/flutter/rendering/RenderClipOval-class.html
https://master-api.flutter.dev/flutter/rendering/RenderClipOval-class.html

The methods that are inherited are italics in the old sidebar, and look exactly like overridden methods in the new sidebar. I noticed this in particular because now noSuchMethod looks like it's overridden by everyone and part of every API.

For reference, I believe this was caused by #2444, I'll submit a PR for this later today or tomorrow.
