Hi, so I was attempting to add a backbar for a ScrollingFrame object. (The blue line you see vertically next to the bright blue slider)
Only to realize this occurs:
For whatever reason, the scrollbar scales larger when the ScrollingFrame scales with the rest of the UI. This is extremely undesirable, as with this happening I have absolutely no way of adjusting my backbar to be symmetrical with the slider bar itself 
It’d be cool if there was a way to enable more of a constant sizing option for the slider, or in other words, maybe more reliable scaling for it, so it shrinks down instead of enlarging in both directions.
Why?
I’ve done lots of testing with tinkering different properties and such; this functionality never changed. This makes it (impossible?) to create accurate back bars for the slider.
