Description
Discussed in https://github.com/testing-library/user-event/discussions/1155 by borja-sanz-sanz
https://github.com/testing-library/user-event/blob/main/src/utils/edit/setFiles.ts lacks a setter.
It's not possible to create a FileList programmatically, but our users could retrieve one from a simulated drag event.
