CommandFeedback does not remove "Trigger x is not enabled" message

Using gamerule "sendCommandFeedback" the trigger command still returns the following message:

"Trigger x is not enabled"
Steps to reproduce: Disable command feedback: "/gamerule sendCommandFeedback false"
Create a trigger: "/scoreboard objectives add test trigger"
Use the trigger: "/trigger test set 1", Not enabled message?

Now try to enable it: /scoreboard players enable @a test
No command feedback? That's how it should be for the not enabled message,

Thanks, Brad
