IMPORT: additional_attributes are completely ignored in 2.2.3

Preconditions

In a Magento admin login, we should have custom attributes created.

1. Navigate to Store>products page: Click on new attribute button, and just add the name of the attribute eg: Cust_Att1. Without any other changes, save the attribute.
2. Navigate to Store>Attribute Set: Click on the default attribute set record, Drag and drop the color attribute and as well the above created Cust_Att1 attribute. Save the attribute set.

Steps to reproduce

1. Prepare a CSV file with below content to import it further.

sku,price,attribute_set_code,product_type,name,additional_attributes
913352,1,Default,simple,ImprotProd5,"cust_att1=ca_edited,color=Blue"
917252,1,Default,simple,ImprotProd6,cust_att1=ca_edited

Note- This above given file data matches according to the above pre condition example data.

2. Navigate to Admin login > System> Import page.
3. Select Entity type- product and import behaviour add/update
4. Select the checkbox - Fields enclosure.
5. Choose the above created file, click on check data and followed by import.
6. Navigate to Catalog>products and search with the SKU text - 913352, and open the product.
7. Check the product's custom attribute value whether that is as per imported file content.

Expected result

Additional attributes should be included along with the other product data.

Actual result

Products get created, but misses to store with the additional attribute column data.

Note: We get to see this issue only when the checkbox Fields enclosure filed is checked while importing in the Import page.

has this been resolved?

i'm having the same issue. i tested 2.1.3 and it worked, upgraded to 2.2.1 and it stopped working. tried in fresh install of 2.3.1 and it is not working. even tried to export the csv, delete the product, and import the csv, but was still ignored.

I can confirm the same issue occurs on 2.2.9. Is this something that is being addressed?

Thanks.
