FileUpload: Set Badges to error in customUpload if file is not valid due to custom validation

Describe the bug

During the custom upload, I first upload two files and check their names according to certain conventions. These files do not pass the test and their badge remains on “Pending”.

If I now upload a correct file, the two invalid files are removed from the upload field and only the valid file remains, whose badge is set to “Completed”.

However, the desired behavior is as follows:

• All files that already exist in the upload field remain there.

• Files that pass the validation are given the “Completed” badge.

• Files that do not pass validation receive the “Error” badge.

Is there a way to implement this behavior?

Steps to reproduce the behavior

1. choose one .png and one .jpg file
2. click on upload

Expected behavior

the .jpg files badge needs to get to error.

Start with the StackBlitz reproducer in src/App.tsx and reproduce the custom upload using one .png and one .jpg file. Inspect the FileUpload custom-upload behavior; done means existing files remain, valid files show “Completed,” and invalid files show “Error” rather than being removed or left pending.
