What's the rationale for having a separate flag for this? Seems like using ENABLE(MODEL_ELEMENT) would be fine.

No real reason other than I just wanted to keep it separate for now. We still need to improve <model> before this could completely replace the WKUSDPreviewView, which is one of the goals.

I think a Setting would be better for this. Seems more useful to have it compiled in and testable, then compiled out.

I'd remove this and replace it with a Setting.

Seems like uint16_t would be more appropriate for the size.

maybe I am missing it, but I think this has any values being concatenated, so this shouldn't use makeString(). Instead, it can just use a " .. "_s.

I would skip all of 50http/tests/model. The feature isn't supported or enabled there so no reason to test it.

Why are these being skipped?

> +http/tests/model/model-document.html [ Skip ]

Again, I would just skip the whole directory.

OK.

This should be changed to be an OptionSet at some point; would be a pretty small change, believe it or not. That does not require using "enum class" in case someone tries to convince you it does, but also this would be a great choice for an enum class since all the values have DocumentClass in their names. Also, the DocumentClass enum should use uint16_t as its underlying type. Also does not require "enum class".

> Source/WebCore/html/ModelDocument.cpp:98

This does not have to be one large line. Can use string pasting to format however you like:

    auto styleContent =
        "body { background-color: white; text-align: center; }\n"
        "@media (prefers-color-scheme: dark) { body { background-color: rgb(32, 32, 37); } }\n"
    ;

Maybe not exactly like that, but something like that.

Just RefPtr is fine, no need to write <Frame>.

> +#endif // ENABLE(VIDEO)

Oops, MODEL_ELEMENT.
