AutomaticCanvasSize on ScrollingFrame does not scale the CanvasSize correctly on some occasions

On some occasions, when the CanvasSize is {0,0}{0,0} on a ScrollingFrame when the AutomaticCanvasSize is set to Y, the scrollbar won’t appear and the ScrollingFrame won’t scroll. However, this gets fixed when resetting the AutomaticCanvasSize by changing it to another one, then back to Y. I cannot get it to happen reliably 100% of the time and happens about half of the time.

I started to notice this bug last year in 2024.

Edit: No scripts make changes to the AutomaticCanvasSize property or the number of items in the list. UIListLayout is used to manage the layout of the children of the ScrollingFrame.

Thanks for you report!
This is a duplicate of `ScrollingFrame.AutomaticCanvasSize` does not work if `Scale` component of `UDim2` is non-zero and part of a larger AutomaticSize refactor.
