Can't select under locked objects when in preview mode
Just to preface this, it may have always been the case but I'm fairly sure it wasn't.
In 2020 when a selection is locked and you're in preview mode you can still select it, this means that if you want to select something underneath (usually the reason I lock things) you can't without moving the thing you're trying to select up or hiding instead of locking. Illustrator tends to add these things and create a checkbox somewhere allowing me to turn it back to how it was before, anybody have an idea how to revert this?
