disableRemove doesn't pass down record object

[andrico1234]

It seems that the following code will always log out an empty object in the console.

<ArrayInput source="resourcePools" label="CP Resource Pools" level={2}>
        <SimpleFormIterator
          disableRemove={record => {
            console.log(record);
            return true
          }}
        >
            ...
        </SimpleFormIterator>
</ArrayInput>

What you were expecting:
To be given the record of the current ArrayInput iterable

Steps to reproduce:
If you go to the repro case

• Navigate to the PostEdit page
• Add a new post_id
• Click save
• Click back into the record

You'll observe that the input is populated, but no data is being passed through to the disableRemove function
