Order Item Fees not calculating inclusive tax correctly

I have set in Tax Options: ‘Yes, I will enter prices inclusive of tax’;

I’m adding an array of order fee items to an order with:

                
$item = new WC_Order_Item_Fee();
$item->set_name( $fee_item['name'] );
$item->set_total( $fee_item['total'] );
$tax_class = (isset($fee_item['tax_class']) && $fee_item['tax_class'] !== 0) ? $fee_item['tax_class'] : 0;
$item->set_tax_class( $tax_class ); // O if not taxable
$item->calculate_taxes($calculate_taxes_for);
$item->save();
$order->add_item( $item );

But these fee items are calculated wrong, tax is being added.
With 10% Tax set
A $9 item becomes $9.00 with $0.90 TAX
When it should be $8.18 with $0.82 TAX

I have to hard code my controller to set the price correctly, but it should really calculate correctly based off the tax classes.
