https://codereview.chromium.org/2728373004 added the following attribute to ImageData.idl:
[RuntimeEnabled=ExperimentalCanvasFeatures] readonly attribute ImageDataColorSettings colorSettings;
However, ImageDataColorSettings is a dictionary, and https://heycam.github.io/webidl/#idl-dictionaries specifically states "Dictionaries must not be used as the type of an attribute or constant".
It looks like the Canvas Color Spec itself needs to be fixed, and the IDL then needs to be updated in Chromium.
