ScrollingFrame doesn't let MouseButton1Up fire

So I found a bug in Studio where you cannot stop moving a part after you have clicked it. Here’s the steps to replicate this bug:

[li]Create a new part[/li]
[li]Put a SurfaceGui into the part[/li]
[li]Put a ScrollingFrame inside of the SurfaceGui[/li]
[li]Click the part on the side that the ScrollingFrame is on and try to drag the part [/li]
[li]You will not be able to stop dragging the part until you somehow get your mouse to move outside of the ScrollingFrame.[/li]

This also happens to ScreenGuis
