prefer_inline: false positive when using interface/class?

[mbtools]

When using global interface and class, it says to use inline declaration. Is there a way to do this in ABAP and avoid the error?

https://github.com/mbtools/TEST_INLINE/runs/3920601749

Program ZTEST_INLINE_GLOBAL:

  DATA li_test TYPE REF TO zif_test_inline.
  li_test = NEW zcl_test_inline( ).
  li_test->test_1( ).

Interestingly, if class/interface are defined locally in the program, as expected, there's no error (see ZTEST_INLINE_LOCAL).
