Filter not working with embedded properties (multiple levels)

I dont know if this relates to https://github.com/api-platform/api-platform/issues/277 but I have a issue with filtering by embedded properties. For example, I have to following entity structure:

• User has Profile
• Profile has Address
• Address has postalCode (string)

So when I call

/api/users?profile.address.postalCode=88

with the filter configuration

filter.search_user:
        parent:    'api_platform.doctrine.orm.search_filter'
        arguments: [ { profile.firstName: 'partial', profile.lastName: 'partial', profile.address.postalCode: 'starts' } ]
        tags:      [ { name: 'api_platform.filter', id: 'filter.search_user' } ]

I would expect a response that only contains users with a postal code starting with 88. But all users are returned since the filter is not applied at all.

The same issue occurs when I call

/api/users?profile.firstName=Thomas

what should return only users with Thomas in their firstName but all users are returned. I digged a lot in the issues and found https://github.com/api-platform/core/pull/242 and https://github.com/api-platform/core/issues/83.

So is this already a feature and/or am I facing a bug?

EDIT: Thought that only occurs with embedded entities deeper that one level. But it seems its not possible to filter by embedded entity properties at all.

Thanks. Can confirm that https://github.com/api-platform/core/pull/984 works like a charm. Also I accidentally used starts instead of start.

@Simperfit should work with as many levels as we need:

Extract of filters services:

    product_referencing.filter.date:
        parent: 'api_platform.doctrine.orm.date_filter'
        arguments: [ { 'fromDate': 'include_null_after', 'thruDate': 'include_null_after' } ]
        tags: [ {name: 'api_platform.filter', id: 'product_referencing.filter.date' }]

    product_referencing.filter.enabled:
        parent: 'api_platform.doctrine.orm.boolean_filter'
        arguments: [ { 'enabled': ~, 'product.productToPackaging.isDefault': ~, 'product.productInternalOrganization.referencingStatus.isBlocking': ~} ]
        tags: [ {name: 'api_platform.filter', id: 'product_referencing.filter.enabled' }]

    product_referencing.filter.product:
        parent: 'api_platform.doctrine.orm.search_filter'
        arguments: [ { 'product': 'exact', 'product.category.id': 'exact', 'product.priceDefinitionFamily.id': 'exact', 'product.code': 'exact', 'product.productInternalOrganization.internalOrganization': 'exact' } ]
