ID 159824 - Corner Pin - when added after rotopaint, roto disappears in this script unless you zoom in

This one is hard to explain but in this script the corner pin added after the rotopaint makes the roto node disappear unless if you zoom in.

I tested on Nuke7.0v6 and Nuke7.0v8 for 10.6.8

Here is the script:

set cut_paste_input [stack 0]
version 7.0 v6
push $cut_paste_input
