支付宝小程序内使用报错TypeError: Cannot read property 'x' of null

如题，错误报出的位置是这里：
https://github.com/antvis/F2/blob/5f2feb660409086ab1fe4f03a2f12422cc8c9b04/src/interaction/mixin/move.js#L23

是不是考虑给 currentPoint 一个默认对象：
https://github.com/antvis/F2/blob/5f2feb660409086ab1fe4f03a2f12422cc8c9b04/src/interaction/mixin/move.js#L22

Inspect src/interaction/mixin/move.js at the referenced lines and reproduce the TypeError in an Alipay mini-program. Verify that the move interaction handles a null currentPoint without accessing its properties, and confirm the reported error no longer occurs.
