like ref to val (val generic typed), expect syntax error

[oblomov-dev]

Abaplint is not showing a syntax error in this situation:

    METHODS my_method
      IMPORTING
        !val          TYPE data.

METHOD my_method.
   DATA lr_data LIKE REF TO val.
ENDMETHOD.

Found this here after installing on an abap system:
https://github.com/abap2UI5/abap2UI5-downport/blob/cdccb5a64b2f0eecb271cfe33f3ed0411b4e0d3b/src/01/02/z2ui5_cl_core_app.clas.abap#L164

Or here (maybe the same issue):

    METHODS my_method
      IMPORTING
        !tab           TYPE STANDARD TABLE OPTIONAL.

METHOD my_method.
    DATA lr_tab LIKE REF TO tab.
ENDMETHOD.

Additionally this code is generated by the downporter, so its also a bug there, but not sure wether fixing the downporter is worth it, because i can fix this easily also on the main codeline. It's a bit similar to this issues:
#2946

reproduced as

CLASS lcl DEFINITION.
  PUBLIC SECTION.
    METHODS my_method
      IMPORTING
        !val TYPE data.
ENDCLASS.

CLASS lcl IMPLEMENTATION.
  METHOD my_method.
    DATA lr_data LIKE REF TO val.
  ENDMETHOD.
ENDCLASS.
