时间设置器TimePicker选择后时间会清空

复现步骤：
将下面配置放到任何一个组件的meta.ts中，将组件拖入画布，选中组件修改当前时间配置，时间会清空。
{
name: 'value',
title: { label: '当前时间', tip: '当前时间' },
setter: 'TimePicker',
},

Start by reproducing the issue with the shown setter configuration in a component's meta.ts, then inspect the TimePicker setter and how its selected value is written back after editing in the canvas. Done means changing the current-time setting no longer clears the selected time.
