"Comparison to null is expensive" and "unity lifetime check" icon on implicit lifetime check, but not on explicit

If you compare a unity object against null, you get the "Comparison to null is expensive" warning and the "implicit check for unity object lifetime" icon.



If you then convert it to the explicit check per resharper suggestion, both hints disappear, even though the check is still performed.



Expected:
Both icon and hint for expensive operation should still be there.

Start by reproducing the Unity object comparison and explicit lifetime-check cases described in the issue, then locate the inspection responsible for the warning and lifetime icon. Done means the explicit check still reports both the expensive-operation hint and the implicit Unity lifetime-check icon, with coverage for both forms if the existing test structure supports it.
