Describe what you thought should happen here

What actually happened was...:
When I click on the tellraw message and the click event value is

and the gamerule commandblockoutput is false it still displays the chat message set score of Testing for "your player" to one. I don't know if this is a bug because technically the tellraw doesn't have to come out of a commandblock but it is anoying to have that message displayed.
