  return { image:formData.get('photo') }
}
.......
<Form replace method="post" encType="multipart/form-data">
 <input
     id="icon-button-file"

looks like we're setting it on creation and never set it to anything else - i've file an internal ticket

Bump.

lastModified is one last missing piece of instance properties of a File() object.

I'm sending it alongside the file as a hidden input state, but if anyone has a better workaround, I'm interested.

<input
  type="hidden"
  name="lastModified"
  value={lastModified ? new Date(lastModified).toISOString() : ''}
/>
