Describe the bug

After an invalid file (not allowed extension) is added, the form can not be sent anymore. Browser says: "Field contains invalid files"

Reproduction

https://codesandbox.io/s/filepond-demo-forked-tzqg9h?file=/index.html:399-400

<form method="post" enctype="multipart/form-data">
    <input type="file" name="filepond" multiple="multiple" accept="image/*" />
    <input type="submit" />
</form>

registerPlugin(FilePondPluginFileValidateType);

const input = document.querySelector('input[type="file"]');

create(input, {
  acceptedFileTypes: ["image/*"],
  storeAsFile: true,
  checkValidity: true
});

Press Browse and add a forbidden file, such as a .mp3 or .exe. Press upload. The browser reports that the form is invalid, which is correct. Add a second, valid file, and remove the invalid file. Press submit. The browser still report that the form is invalid, which is not correct this time.

Environment

- Device: PC
- OS: Windows 11
- Browser: Edge 131, Firefox 134
