Disabled TextInput in SimpleForm returns undefined

[Netail]

What you were expecting: Disabled TextInput value is passes initial value back

What happened instead: Disabled TextInput value is passed back as undefined

Steps to reproduce: Have a SimpleForm with a TextInput which has a disabled field for the edit page, which gets preloaded with an initial value, when saving it returns undefined

export const Edit = (): JSX.Element => {
  const { id } = useParams();
  return (
    <Edit id={id}>
      <SimpleForm warnWhenUnsavedChanges>
        <TextInput
          label="Ingredient Name"
          source="name"
          disabled
        />
      </SimpleForm>
    </Edit>
  )
}

Not sure if this is default behaviour, to set disabled input values to undefined, but something you want to use them as a display. Maybe an option for this would be nice?
