ArrayField sortable={false} console warnings

[blamze]

Description:
Adding sortable={false} in ArrayField component prints react warrnings in console (but it disables sorting)

console error
Warning: Received false for a non-boolean attribute sortable.
If you want to write it to the DOM, pass a string instead: sortable="false" or sortable={value.toString()}.
If you used to conditionally omit it with sortable={condition && value}, pass sortable={condition ? value : undefined} instead.

Actually, in all cases if you put it like
<ArrayField source="categories" sortable}>
or
<ArrayField source="categories" sortable={true}>
it says it want non-boolean , but if you provide string - it says it wants boolean
(Warning: Failed prop type: Invalid prop sortable of type string supplied to EnhancedArrayField, expected boolean.)

What you were expecting:
Clean console

What happened instead:

Steps to reproduce:

<ArrayField source="categories" sortable={false}>
  <SingleFieldList>
     <ChipField source="title" />
  </SingleFieldList>
</ArrayField>

Environment
"react": "16.8.6",
"react-admin": "2.8.6",

hey guys, I use ArrayField with Datagrid:

<ArrayField source="jobs">
  <Datagrid>
    <TextField source="status" />
    <TextField source="error" />
    <DateField source="updated_at" showTime />
  </Datagrid>
</ArrayField>

and now I see error on click column header:

Datagrid.js:162 Uncaught TypeError: _this.props.setSort is not a function
    at Datagrid._this.updateSort (Datagrid.js:162)

is this related with topic issue?
