New description:
ClearableFileInput widget forgets "Clear" selection when form is not
valid, that causes file would not be deleted once when form is valid
again. This can be inconvinient, especially for forms with many fields.
To reproduce:
1. Choose admin for any model instance where attachment is not required
and has some validation,
2. check "Clear" next to the attachment, and change the form, so
validation would fail,
3. Save form, validation error would occur, attachment and "Clear" would
be empty
4. make form valid again and Save, attachment woult not be cleared
(I am attaching example screenshots)
