crud在body中filter-group无法获取page的initApi数据

[JokerCrying]

如题，amis配置如下
{
"aside": [
"\n

\n 类别选择\n

\n ",
{
"type": "divider"
},
{
"className": "font-bold",
"source": "${navSource}",
"stacked": true,
"type": "nav"
}
],
"body": [
{
"columns": [
{
"label": "id",
"name": "id",
"type": "text"
},
{
"label": "name",
"name": "name",
"type": "text"
}
],
"filter": {
"actions": [
{
"icon": "fa fa-refresh fa-spin",
"label": "重置",
"level": "default",
"size": "sm",
"type": "reset"
},
{
"icon": "fa fa-search",
"label": "查找",
"level": "primary",
"size": "sm",
"type": "submit"
}
],
"body": [
{
"label": "品质",
"name": "ship",
"size": "md",
"source": "${fliterSource.ship}",
"type": "select"
},
{
"label": "限制",
"name": "limits",
"size": "md",
"source": "${filterSource.limits}",
"type": "select"
},
{
"label": "外观",
"name": "appearance",
"size": "md",
"source": "${filterSource.appearence}",
"type": "select"
}
],
"mode": "inline",
"title": "",
"type": "group"
},
"footerToolbar": [
"switch-per-page",
"statistics",
"pagination"
],
"perPageField": "per_page",
"syncLocation": false,
"type": "crud"
}
],
"initApi": "get:/source/getXXXSource"
"debug": true,
"type": "page"
}
那么现在问题来了，边栏里的nav可以直接拿到navSource，但是在curd中的fliter中就无法拿到filterSource，是新bug还是本来就有这个问题，可以解决一下吗
