Tellraw commandblockoutput

Put the summary of the bug you're having here
Tellraw outputs what it did even if the gamerule commandblockoutput is set to false

What I expected to happen was...:
When I click on a tellraw command it should do what the click event told it to do.
Describe what you thought should happen here

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

{"/scoreboard set @p Testing 1}

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.

Steps to Reproduce:
1. Write a tellraw command that sets a scoreboard to for example 1
2..Set the gamerule commandBlockOutput to false
3. Click on your tellraw command and get a output.
