When I click Pull and view "Show Full Output" I see:

>git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks fetch --no-tags origin

>git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks pull --no-commit origin staging

This is unnecessary, since a "pull" is literally a fetch+merge
>git pull runs git fetch with the given parameters

Running fetch first is just making it unnecessarily slow - especially if your network is slow.
