It's weird to be caching in a public getter.

It opens us up for problems

If some client code (for whatever reason) did 
connect(scope, inheritChanged, []() {scope->colorGroup());

then our signals in checkColorGroupChanged won't get emitted.

Can we move this member var into checkColorGroupChanged? Means we can get rid of the mutable too
