References created using CreateDynamicVariable and WriteOrCreateDynamicVariable cannot be accessed immediately #3909

Describe the bug?

When you create a DynamicReferenceVariable using LogiX you have to wait 3 updates until you can read from/write to it.

Relevant issues

I haven't found any issue describing the same problem.

2012 is related in a way that it also suffers from the delayed linking proces of DynVars.

To Reproduce

  1. Create a new dynamic reference variable using CreateDynamicVariable or WriteOrCreateDynamicVariable nodes
  2. Read from/write to that variable using LogiX nodes directly following the variable creation.
  3. Reading/Writing will fail. ("not found")
  4. After 3 update delays it will work.

Expected behavior

Reading/writing should work immediately

Did this work before?

I Don't Know

If it worked before, on which build?

No response

Additional context

DynamicVariableHelper.CreateVariable(...) calls DynamicValueVariable.UpdateLinking() for primitive types. DynamicVariableHelper.CreateReferenceVariable(...) on the other hand does not.

A workaround is to store RefIDs and unpack them using some write node/Reference typed field trickery.
