## Description
If you have an `addForeignKeyConstraint` change with attribute `deleteCascade="true"` it is simply ignored.
This code: https://github.com/liquibase/liquibase/blob/43ed0e54adedc5f12c7933b998550e777d9b683d/liquibase-core/src/main/java/liquibase/change/core/AddForeignKeyConstraintChange.java#L195-L199 suggests that it should be automatically translated to `onDelete="CASCADE"` which would make sense, but it is not.
It currently is simply ignored.
