left direction ignored when pointing from inside a namespace to sub namespace

Question

Example:

@startuml

namespace ns1 {
  class A
  namespace ns2 {
    class B
  }
}
ns1.A -left- ns1.ns2.B

class C
namespace ns3 {
  class D
}
C -left- ns3.D

@enduml

Expected result: class B should be left from A, just like D is left from C.

Using packages instead of namespaces doesn't help.

Hello E.,

Using packages instead of namespaces doesn't help.

No, using packages can help, but we lost the power of namespace...

As workaround, we can combine 'package' and 'together' (for only one element!) as it:

package ns1 {
  together {
    class A
  }
  namespace ns2 {
    class B
  }
}
A -left- ns2.B

Then we observe the expected result:

Expected result: class B should be left from A, just like D is left from C.
