@lakesare lakesare commented Aug 1, 2024

This PR:

  • created a proper demo of the bug event.target.value = '' is preventing, added that demo to the comments
  • properly type the text input event: we go from ChangeEvent to TargetedEvent<HTMLInputElement, Event>
  • everything else (target => currentTarget, null => '') is a consequence of the correct typing

New version is tested in:

  • Firefox
  • Chrome
  • Safari

Testing consists of:

  1. make sure uploading a duplicate file always triggers onBeforeFileAdded
  2. make sure currentTarget.files actually has files

I assume you checked that using currentTarget in place of target is safe (e.g. they seem to differ with regards to bubbling)
