[kevinchangm]

"@antv/layout"依赖的库 "@antv/g-webgpu": "0.5.5",存在不，会导致使用装饰器的页面挂掉，请帮助尽快修复下 bug修复地址：https://github.com/rbuckton/reflect-metadata/pull/107

exporter("deleteMetadata", deleteMetadata);
    function DecorateConstructor(decorators, target) {
        for (var i = decorators.length - 1; i >= 0; --i) {
            var decorator = decorators[i];
            var decorated = decorator(target);
            if (!IsUndefined(decorated) && !IsNull(decorated)) {
                if (!IsConstructor(decorated))
                    throw new TypeError();
                target = decorated;
            }
        }
        return target;
    }
