UEditorValidatorBase::ValidateLoadedAsset() is not using the K2_ValidateLoadedAsset() output, effectively ignoring the Blueprint validation

UEditorValidatorBase::ValidateLoadedAsset() is not using the K2_ValidateLoadedAsset() output, effectively ignoring the Blueprint validation.
The K2Result is not used later in the function, and this reflects on the verification being ignored, as exemplified by the repro steps provided.
The behavior changed. It previously worked up to version 5.3, but after 5.4 up to 5.6 (CL42031367) it stopped working, so I've marked it as a Regression.

Create an Empty blank project
Open editor & right click in content browser click "Editor Utilities-> Editor Utility Blueprint" & set parent class to EditorValidatorBase.cpp, and save (name it, for instance, EUB_Repro)
Override CanValidate and CanValidadeAsset functions making both return true
Override the ValidateLoadedAsset function and return Invalid
Create any asset (for instance, an actor BP named BP_TestAsset), and save
Close and reopen the project to register the Validator
Edit the created Asset (BP_TestAsset) and save

Expected result: we should get a Message Log warning us that the validation returned Invalid (this is the behavior on 5.0, 5.1, 5.2, 5.3)
Actual result: there is no warning, the Asset is saved and the Invalid return is ignored. Notice that the BP is run, but the invalid result is not logged, as it can be verified in the logs (names from my repro project):
