Drupal Commerce: Entity extra field on product collides with entity extra field on product_variation

Okay finally found it. The issue is, that currently the config is missing the entity type entirely! Just the bundle is added!

So if two entities have the same bundle name, they will conflict!

Example:
entity_extra_field.extra_field.entity_extra_field.glas_plate.boilerplate_body.yml

The bundle glas_plate exists both in commerce_product and commerce_product_variation entities!

The correct configuration name would be:
entity_extra_field.extra_field.entity_extra_field.commerce_product.glas_plate.boilerplate_body.yml
entity_extra_field.extra_field.entity_extra_field.commerce_product_variation.glas_plate.boilerplate_body.yml

So the bundle gets prefixed by the entity type!

Setting priority to major as this is a risky bug.

Please check, if this is the correct approach. For non-bundleable entity types this will (correctly) use the entity type id twice.
