> On root canvas level PG1 and PG2 are created. User1 and user2 have access to
> PG1 while only user2 has access to PG2. User1 or user 2 creates a processor
> and corresponding CS in PG1. At this time both user1 and user2 can disable
> and modify that CS. User2 then copies the processor referencing that CS in
> PG1. That snippet is then pasted inside of PG2. Since PG2 is not a sub
> process group of PG1 the CS referenced in that copied snippet by UUID is out
> of scope for that pasted processor. The CS in PG1 still sees that referencing
> processor from PG2 and now user1 can no longer disable and modify the CS in
> PG1.
> The pasted processor is clearly out of scope of referenced CS. The processor
> would still present as invalid when pasted and still reference the CS's UUID
> in its snippet until property was updated or until processor was moved to a
> new location that was within scope of the CS. The fix here would be to make
> sure the CS does not reference any processors that are out of scope. So in
> this specific scenario it would not block.
