```
{
"type": "page",
"body": {
"title": "",
"type": "form",
"mode": "horizontal",
"autoFocus": false,
"body": [
{
"type": "combo",
"name": "combo101",
"label": "组合多条多行",
"multiple": true,
"multiLine": true,
"value": [
{}
],
"tabsMode": true,
"tabsStyle": "card",
"tabsLabelTpl": "aaaaaaaaaaaaaaaaa",
"maxLength": 3,
"items": [
{
"name": "a",
"label": "文本",
"type": "input-text",
"placeholder": "文本",
"value": "",
"size": "full"
},
{
"name": "b",
"label": "选项",
"type": "select",
"options": [
"a",
"b",
"c"
],
"size": "full"
}
]
}
],
"submitText": null,
"actions": []
}
}
```

4. 操作步骤

Reproduce the issue in the amis SDK with the supplied combo schema, especially the long tabsLabelTpl value and tabsMode configuration. Start by tracing the combo tabs UI from that reproduction; done means the delete button remains clickable when a tab title is too long.
