[Inject] not working on Strip Code - High

[processgamess]

[Inject] attribute works good on 6000.4.9 with strip engine code high but In 6000.5.6, Unity strips [Inject] attributes or something else, it doesnt work.

noticed the same in Unity 6.6, InjectAttribute gets stripped on level medium, preserve all in link.xml does not help.
