Deltalog for catalog_product_super_attribute_pricing is not installed

Preconditions

1. Magento 1 version 1.7.0.2
2. Magento 2 version 2.4.1
3. Magento 1 database has a prefix

Steps to reproduce

1. Run migration tool with data
2. The config.xml has a value for source_prefix
3. Try running the migration a second time with mode delta

Expected result

1. The migration should run a second time and only bring in new records.

Actual result

1. Get an error that Deltalog for catalog_product_super_attribute_pricing is not installed

Additional notes

With a bit of blind stabbing, I found this file src/vendor/magento/data-migration-tool/src/Migration/Step/ConfigurablePrices/Delta.php on line 39 has the following
private $sourceDocumentName = 'catalog_product_super_attribute_pricing';

When I edit that to private $sourceDocumentName = 'm2_cl_catalog_product_super_attribute_pricing'; (All I did was add the m2_cl_ prefix) it works like a charm.

I found a few stack exchange posts where people reported similar missing delta log tables even though they had already ran the data migration.

Start in src/vendor/magento/data-migration-tool/src/Migration/Step/ConfigurablePrices/Delta.php, especially the sourceDocumentName at line 39, and review how source_prefix affects delta-log table names. Reproduce a second migration in delta mode using the reported Magento versions and prefixed database, then confirm it completes and imports only new records.
