Dolphin Changes my Display Refresh Rate

[Trusty McLegit]

I've got a 144hz monitor I have set to 120hz to be more comparable with 60fps games. This works perfectly in windowed and full screen no problem, except for when I press TAB (fps limiter) in fullscreen the screen goes black for a moment, and then my screen is reverted to 60hz. If I'm in windowed mode I can use TAB and it will leave my refresh rate alone, but if I'm in boarderless or exclusive fullscreen it will change my monitors refresh rate.
