3. 操作步骤
   请简单描述一下复现的操作步骤...

Start by reproducing the reported behavior with the provided amis schema, focusing on the combo's delete button and its confirmText in amis 6.8.0 or the latest beta. Check whether cancelling the confirmation preserves the item and confirming removes it; the issue is done when both actions behave correctly.
