[Bug]: Possible inconsistency in how CtComment is handled in CtFieldReferenceImpl

[CoreRasurae]

Describe the bug

Comments can be added to CtFieldReferenceImpl, but they are not considered for cloning and equals methods. Given that comments are disallowed for references in general then why can we add them to CtFieldReferenceImpl and they get stored?
Maybe it is just a misunderstanding of mine, but there seems to be an inconsistency in how this is handled compared to other Ct elements, as for example there are other Ct references that discard the comments when they are added.

Source code for your Spoon processing

@Test
    public void spoonTest() {
        spoon.support.DefaultCoreFactory dfc = new DefaultCoreFactory();
        spoon.compiler.Environment e = new spoon.support.StandardEnvironment();
        spoon.reflect.factory.Factory f = new spoon.reflect.factory.FactoryImpl(dfc, e);
        CtComment cmt = f.createComment();
        cmt.setContent("This is a comment");
        CtFieldReference<String> cfr = f.createFieldReference();
        cfr.setSimpleName("field1");
        //NOTE: References do not allow comments to be set... but we can add one... 
        //that it is not cloned, but preferably it should not be added either...
        cfr.addComment(cmt);
        cmt.setParent(cmt);
        
        assertEquals("FieldReference should have one comment", 1, cfr.getComments().size());
        
        CtFieldReference<String> clonedCfr = cfr.clone();
        assertEquals("Cloned and original objects should be equal", cfr, clonedCfr);
        assertEquals("Cloned object should have one comment", clonedCfr.getComments().size());
    }

Actual output

java.lang.AssertionError: expected:<Cloned object should have one comment> but was:<0>
	at org.junit.Assert.fail(Assert.java:89)
	at org.junit.Assert.failNotEquals(Assert.java:835)
	at org.junit.Assert.assertEquals(Assert.java:120)
	at org.junit.Assert.assertEquals(Assert.java:146)
	at FieldReferenceImplTest.spoonTest(LaastFieldReferenceImplTest.java:17)

Expected output

If comments are not supported for references, then why can we add one to CtFieldReference? I believe that at a minimum the addComment(...) should discard the comment, or an exception should be thrown.
