Should we add tests cases for format strings that have unusual characters in them, like a double quote mark?

Exotic, but we are not attempting to correctly handle such cases it seems.

This is a good idea. I'll do this.

It's a good thing you caught this - this patch is actually wrong. It should be using serializeString() instead.

To fix the URL serialization, we need to consider an approach like the one in CSSImageValue, which uses the ResolvedURL structure to work with both the original specified URL string and a resolved URL.

I thin this is a typo and should be "from".

Looks like these are now wrong. Worth updating or maybe just deleting?

The reason I had to do that is that the same object, CSSImageValue, is used in the  CSS object model both for style rules, where it needs to be the original specified URL, and for computed style where it needs to be the complete URL. And yet the completion needs to be based on where it was specified. Currently this class is used both as part of the "truth" for the style rule, and as the interface to query both original and computed style. Some day we might separate those functions, but in the mean time we need this, and the valueWithStylesResolved function, called by Style::BuilderState::resolveImageStyles, has a key role in how this is used for computed style.
