Updating nested EmbeddedDocumentListField objects

I have trouble pulling nested embedded objects.

Having a model like the following I know we can remove embedded objects as following:

class TopClass(Document):
name1 = StringField()
somevar = EmbeddedDocumentListField(EmbeddedClass)

class EmbeddedClass(EmbeddedDocument):
name2 = StringField()

topclass = TopClass.objects.get(name1=name)
topclass.update(pull__somevar__name2="whatever")

Is there a way to remove an object one level deeper as follows?

class TopClass(Document):
name1 = StringField()
somevar = EmbeddedDocumentListField(EmbeddedClass1)

class EmbeddedClass1(EmbeddedDocument):
name2 = StringField()
someothervar = EmbeddedDocumentListField(EmbeddedClass2)

class EmbeddedClass2(EmbeddedDocument):
name3 = StringField()

topclass.update(something here)

How can i select some EmbeddedClass1 object with name2="something" and then pull (delete) some EmbeddedClass2 object with name3="somethingelse"? (and then save topclass although update should already do it)

Start with MongoEngine's update and pull handling for the nested EmbeddedDocumentListField model shown in the issue. Verify whether an update can select EmbeddedClass1 by name2 and remove a nested EmbeddedClass2 by name3; done would be a documented answer or a focused behavior change with regression coverage.
