description.changed does not trigger workflow on reported issues

Hello,

If I enable the stateless rule below, after the description has been changed, the rule is not triggered.

when description.changed && isReported(){
     addComment("The description has changed");
}

When using the rule below, it works as expected.

when State.changed && isReported(){
     addComment("The State has changed");
}

I have checked issue: JT-14107 , but I still cannot seem to get this to work.
Is there something I am misunderstanding?
