看到 https://github.com/uxcore/uxcore-form-field/blob/master/src/FormField.jsx#L134 这里有对 force / instant 做优先级判断。 实际上，直接在 https://github.com/uxcore/uxcore-form/blob/master/src/Form.jsx#L36 中，先行判断 force 为 undefined 时，返回 `{ values: deepcopy(me.data) }` 会有什么问题么？

Version 4.4.6 introduced multiple `...` syntaxes in the build results, which caused incompatibility issues with lower version browsers.   

Although browsers that do not support the `...` syntax are too old, this change should be a major version upgrade rather than a minor version change.
