As this is a Quirk can be append Quirk?

I have no problem with adding it, although, I would like to hear what other
reviewers think about this.

Adding "Quirk" sounds fine to me.

Maybe name it ViewportMetaLayoutSizeQuirk?  And invert the meaning of the bool
so that if "true" then it is the WebView quirk.

Done.
