DisplayRepresentation.Image(systemName:tintColor:) ignores or misapplies tintColor since iOS 18

DisplayRepresentation.Image(systemName:tintColor:symbolConfiguration:) no longer applies the provided tintColor reliably since iOS 18. Observed behavior by OS version:

• iOS 17: SF Symbol tint is applied consistently as expected.
• iOS 18: SF Symbol tint is inconsistent and sometimes appears with incorrect or seemingly random colors instead of the provided tintColor.
• iOS 26: SF Symbol is rendered without any tint (default monochrome), completely ignoring the provided tintColor.

This appears to be a regression in how App Intents renders DisplayRepresentation.Image with tinting across OS versions.

struct CategoryEntity: AppEntity, Hashable {
    var id: Category.ID
    var name: String
    var icon: Int?
    var color: Int?
    var parentCategoryName: String?
    
    init(from category: Category) {
        self.id = category.id
        self.name = category.name
        self.icon = category.icon
        self.color = category.parent?.color ?? category.color
        self.parentCategoryName = category.parent?.name
    }
    
    var displayRepresentation: DisplayRepresentation {
        DisplayRepresentation(
            title: "\(name)",
            subtitle: parentCategoryName.map { "\($0)" },
            image: .init(
                systemName: Icon.sfSymbolName(from: icon),
                tintColor: ColorTag.from(color)
            )
        )
    }
    
    static let typeDisplayRepresentation: TypeDisplayRepresentation = "Category"
    
    static let defaultQuery = CategoryQuery()
}
