dateTime组件，在sdk下报错（移动端）

引用sdk ，1.9.0版本
let amis = amisRequire('amis/embed');
let amisJSON = {
"type": "page",
"body": {
"type": "form",
"api": "/amis/api/mock2/form/saveForm",
"body": [
{
"type": "input-datetime",
"name": "datetime",
"label": "日期时间"
}
]
}
}
let amisScoped = amis.embed('#root', amisJSON)
点击选择时间报错，如下：
TypeError: Cannot read properties of null (reading 'parentNode')

Reproduce the issue using the provided amis/embed configuration with SDK version 1.9.0 and the input-datetime field, then trace the resulting null parentNode error from the date-time selection flow. Done means selecting a date and time no longer throws the reported TypeError in the mobile SDK scenario.
