Why Abstract=True dosen't inherit in Meta class of django model

I we have this models in django:

class FotherModel(models.Model):
    # Some fields goes here! 
    class Meta: 
        # Some fields goes here! 
        abstract = True 
class ChildModel(FotherModel):
    # Some fields goes here! 
    class Meta(FotherModel.Meta):
        #s Some fields goes here! 

When we inherit a field from the meta class of Django models, that field appears in child meta class, But this rule does not apply to abstract=True.

I know that if this happens, no table in database will be created, But I don't know how this inheritance didn't happen. Please explain this process for me.

The Model metaclass resets abstract in a model's Meta class. In this document you can see:

Django does make one adjustment to the Meta class of an abstract base class: before installing the Meta attribute, it sets abstract=False. This means that children of abstract base classes don’t automatically become abstract classes themselves.

Also, you can see the source code of this process in this link:

if abstract:
    # Abstract base models can't be instantiated and don't appear in
    # the list of models for an app. We do the final setup for them a
    # little differently from normal models.
    attr_meta.abstract = False
    new_class.Meta = attr_meta
    return new_class
