See Sam Weining comment on https://github.com/WebKit/WebKit/pull/54635#discussion_r2583134648

Please consider using the switchOn() form here. While a bit more verbose, I think it ends up making things more clear.

WTF::switchOn(styleLogicalHeight,
    [&](const Style::PreferredSize::Fixed& fixed) {
        ...
    },
    [&](Style::IsPercentageOrCalc auto const& percentageOrCalc) {
        ...
    },
    [&](const CSS::Keyword::FitContent&) {
        ...
    },
    [&](const CSS::Keyword::WebkitFillAvailable&) {
        ...
    },
    [&](const CSS::Keyword::MinContent&) {
        ...
    },
    [&](const CSS::Keyword::MaxContent&) {
        ...
    },
    [&](const CSS::Keyword::Intrinsic&) {
        ...
    },
    [&](const CSS::Keyword::MinIntrinsic&) {
        ...
    },
    [&](const CSS::Keyword::Auto&) {
        ...
    }
);
