Allowing Toggle Conflicts Doesn't let me set same hotkey for Observer Abilities

I feel like this issue has been around for quite some time, and I have seen one other post about it on the other forums so far. It’s exactly as the title says. I enable the option Allow Toggle Conflicts (It allows users to set the same hotkey for abilities that work like a toggle) but it still doesn’t allow me to set the same hotkey for the Protoss Observer’s ability. Warp Prism works absolutely fine though.

From a programming point of view I can kind of see why this issue occurs though.

Of course this still wasn’t fixed…

Yep, still not fixed.

Still not fixed!
Please Blizzard! If it can work for the warp prism and oracle, i guess it can work for the observer as well!?
