// Is
var xxxOptions = new XXXOptions(
    false
)
{
    XXOptions = XXOptions,
    XXXXXXXXXXXXMode = XXXXXXXXXXXMode.Active,
};

// ShouldBe
var xxxOptions = new XXXOptions(false) {
    XXOptions = XXOptions,
    XXXXXXXXXXXXMode = XXXXXXXXXXXMode.Active,
};

Another related edge case that can probably be handled at the same time, the space brace wasn't consistent.

new Node(
    "keyD",
    "D inserted",
    new Node("keyB1", "D1") { IsNew = true }, // Matches an old key, but treated as new because we don't move between parents
    new Node("keyD2", "D2") { IsNew = true },
    new Node(null, "D3 unkeyed") { IsNew = true }
) {
    IsNew = true
},
