Baseline dates are computed in groups, and this one has been attributed to the "object" group, here: https://github.com/web-platform-dx/web-features/blob/eae1f06f186a83d004c125d90856498ce3d9f726/features/object-object.yml.dist#L306 so it does not reflect the support of the specific method itself. This is discussed in mdn/yari#11546.
