Config dependencies not getting added to Feature export

Exporting config to a Feature doesn't add the dependencies of the config to the feature itself.

For example, a taxonomy reference field_storage has a dependency on the "taxonomy" module. The "taxonomy" module is not providing any config, but is a dependency. If I generate a Feature Module A that contains this field_storage, it's important to add "taxonomy" as a dependency to this feature module. Otherwise during a site install Drupal can attempt to enable my Feature Module A *before* Taxonomy is enabled, causing UnMetDependencies errors.

To test this:

1) Create new feature
2) Add a field_storage for a field that has a module dependency
3) Generate the feature

the features.info.yml doesn't have any dependency in it.

Seems like the dependencies are set in the FeatureManager::assignConfigPackage() function. But this function isn't called when adding new items to a new feature?

From nedjo:

As you note, it's supposed to be handled by these lines in FeaturesManager:assignConfigPackage():

          // For configuration in the InstallStorage::CONFIG_INSTALL_DIRECTORY
          // directory, set any module dependencies of the configuration item
          // as package dependencies.
          // As its name implies, the core-provided
          // InstallStorage::CONFIG_OPTIONAL_DIRECTORY should not create
          // dependencies.
          if ($config_collection[$item_name]->getSubdirectory() === InstallStorage::CONFIG_INSTALL_DIRECTORY && isset($config_collection[$item_name]->getData()['dependencies']['module'])) {
            $module_dependencies = array_merge($module_dependencies, $config_collection[$item_name]->getData()['dependencies']['module']);
          }
