[Bug]: Downloading the signature clears the signature and the downloaded image is empty

What happened?

I have made the fields downloadable, and when pressing download, the signature is downloaded, but the file is empty and it clears the signature field.

How to reproduce the bug

Create a filed of type Signature, make it downloadable, press the download

                SignaturePad::make('signature')
                    ->required()
                    ->downloadable(),
