make:entity with multiple mappings fails

Using bundle v. 1.26.1 with symfony 4.4

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'

        # IMPORTANT: You MUST configure your server version,
        # either here or in the DATABASE_URL env var (see .env file)
        #server_version: '13'
    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
        auto_mapping: true
        mappings:
            AppCommon:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Common/Entity'
                prefix: 'App\Common\Entity'
                alias: AppCommon
            AppApi:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Api/Entity'
                prefix: 'App\Api\Entity'
                alias: AppApi
            AppDb:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Db/Entity'
                prefix: 'App\Db\Entity'
                alias: AppDb

The following configuration is a valid one, but make:entity does not allow for files to be generated in those mappings, falling back to an unconfigured one which exists by default.
It creates new folders under src/ (entity and repository) for any class I type in
Something like bin/console make:entity AppDb\Something also fails.

It should generate the entity in src/Db/Entity and it just makes it in /src

Start with the make:entity command and reproduce the issue using the three Doctrine mappings shown in the report. Compare entity generation with and without an explicit AppDb\Something class name. Done means generated entity and repository files are placed in src/Db/Entity and its configured repository location rather than a default src/ directory.
