Product flat table - Incorrect data

[tranhoangthien1990]

We're current facing an issue that the product data has been inserted to an incorrect flat table.

Preconditions (*)

1. Magento version 2.3.3 with Sample Data
2. Enable Catalog Product Flat.
3. Index mode for Catalog Product Flat: Update on save

Steps to reproduce (*)

1. Create 2 new websites, for each website, create one store view (let say the store view id for website 1 is 2, store view id for website 2 is 3).
2. Come to any product detail, try to assign this product to website 1, then click Save.

Expected result (*)

1. Product information just insert to flat table of the website that product is assigned to (in this case, this table is catalog_product_flat_2)

Actual result (*)

1. Product information has been inserted for all product flat table (in this case, include catalog_product_flat_3)

After i run php bin/magento indexer:reindex catalog_product_flat all invalid data has been removed (in this case, this product information has been removed in catalog_product_flat_3 ).
Please help to check it again.
Thanks.
