MigrationGroup shared configuration breaks UI

From Migrate Plus:

MigrationGroup configuration entities [...] allow configuration to be shared among multiple migrations.

Shared configs works beautifully whenever we run such migrations via Drush, or trigger them programmatically. However, they break the UI provided by Migrate Tools. Either visiting an individual migration page (/admin/structure/migrate/manage/<migration_group>/migrations/<migration>) or trying to trigger an import (/admin/structure/migrate/manage/<migration_group>/migrations/<migration>/execute) fail with:

The website encountered an unexpected error. Please try again later.
TypeError: Argument 1 passed to Drupal\migrate\Plugin\Migration::getProcessNormalized() must be of the type array, null given, called in /app/web/core/modules/migrate/src/Plugin/Migration.php on line 640 in Drupal\migrate\Plugin\Migration->getProcessNormalized() (line 396 of core/modules/migrate/src/Plugin/Migration.php).

While Migrate Plus is responsible for the shared group configuration functionality, since the failure is in the UI, provided by Migrate Tools, I'm posting this bug report here.
