fileList that's in control not trigger onChange status update when the file is not in the list?onChange will only trigger when the file is in the list, it will ignore any events removed from the list. Please note that there does exist a bug which makes an event still trigger even when the file is not in the list before 4.13.0.
onChange sometimes return File object and other times return { originFileObj: File }?For compatible case, we return File object when beforeUpload return false. It will merge to { originFileObj: File } in the next major version. Current version is compatible to get origin file by info.file.originFileObj. You can change this before a major release.
Chrome update will also break native upload. Please restart Chrome to finish the upload work.
