A related issue from #1573 is that when loading a .ora file, the bottom-most layer actually ends up being the selected layer because we don't do anything specific to configure this.
I think the top-most, or at least the top-most visible layer, would maybe be a more intuitive default?
There is also an extension for storing info about the selected layer in .ora files: https://www.openraster.org/extensions/layer-selection-status.html
