[BUG] Problem in canceling file upload

Environment

Please provide as many details as you can:

• Hosting type
  • Form.io
  • Local deployment
• Formio.js version: 4.10.0-rc.2
• Frontend framework: Javascript
• Browser: Chrome
• Browser version: 83

Steps to Reproduce

1. Upload a large file
2. Try to stop uploading before finishing (The uploading file will be deleted from the UI)
3. But file continues to be uploading behind the scene, and finally it will be added to the list of uploads

Expected behavior

The file should not be uploaded to the server and displayed in the UI.

Example

The definition of form is as follows:

{
    "display": "form",
    "components": [
        {
            "label": "Upload File",
            "storage": "url",
            "dir": "target/folder",
            "fileNameTemplate": "{{guid}}",
            "filePattern": "*",
            "fileMinSize": "0KB",
            "fileMaxSize": "1GB",
            "multiple": false,
            "type": "file",
            "url": "/path/to/upload",
            "input": true,
            "key": "uploadFile",
            "id": "eventfq"
        }
    ]
}

This has been working. I believe it can be closed.
