this.$scopedSlots is undefined if component doesn't have scoped slot

Steps to reproduce

Check console

What is Expected?

I think it would be nice to have this.$scopedSlots as empty object (match this.$slots) if component doesn't have scoped slot. Would be easier to use in an if condition if (this.$scopedSlots.named) {} instead of if (this.$scopedSlots && this.$scopedSlots.named) {}
