Product Customizable Options Value, can't save SKU value

[SvanteAvenla]

Preconditions

1. Magento CE 2.2.3
2. PHP 7.0.30

Steps to reproduce

1. Create a new Simple product.
2. Add a new Customizable Option ('Option Title' => 'Radio', 'Option Type' => 'Select - Radio Buttons').
3. Add two Option Values with these values:
   ['title' => 'One', 'Price' => '10', 'Price Type' => 'Fixed', 'SKU' => 'Performance problem & memory leak in Mage_Index_Model_Process #123'],
   ['title' => 'Two', 'Price' => '20', 'Price Type' => 'Fixed', 'SKU' => 'Bogus error message if mcrypt extension is not installed. #456']
4. Fill the rest of the required information to be able to save the new product.
5. Save the product.
6. Edit the products Customizable Option, change the Option Values to these values (SKU's are the same):
   ['title' => 'One', 'Price' => '10', 'Price Type' => 'Fixed', 'SKU' => 'Performance problem & memory leak in Mage_Index_Model_Process #123'],
   ['title' => 'Two', 'Price' => '20', 'Price Type' => 'Fixed', 'SKU' => 'Performance problem & memory leak in Mage_Index_Model_Process #123']
7. Save the product.

Expected result

1. The product should contain a Customizable Option with two Option Values, both with SKU set to 'Performance problem & memory leak in Mage_Index_Model_Process #123'.

Actual result

1. The product contains a Customizable Option with two Option Values, the first with SKU set to 'Performance problem & memory leak in Mage_Index_Model_Process #123' and the second with SKU set to 'Bogus error message if mcrypt extension is not installed. #456'.

Additional notes

The SKU value is unset in the function Magento\Framework\Model\ResourceModel\Db->prepareDataForUpdate($object).
