+1 Got this issue too… Would be great !
You don’t have to set the element (e.g. the background image) which has an absolute position to the top.
Just to make sure you set the order of the parent auto-layout frame to
first on top (have a look at the image attached).
I’m having the same issue while creating an agenda table view where some elements need to be fixed below others that scroll.
I’m pretty sure you could do this on older versions of Figma, wich is weird.
