ID 525908 - A Crop node's box will sometimes be displayed in the wrong position in the Viewer, when there is a downstream AppendClip node

Problem summary
A Crop node's box will sometimes be displayed in the wrong position in the Viewer, when there is a downstream AppendClip node.
 
Customer reported version
N/A
 
Customer reported platform
Windows 10
 
Steps to reproduce
 
1) Open Nuke.
 
2) Create a CheckerBoard node.
 
3) Create number of Crop nodes (8 in this example) downstream of the CheckerBoard. 
 
4) On each Crop node, adjust the size and position of the box to different sizes/positions.
 
5) Attach all of the Crop nodes to an AppendClip node.
 
6) Go to Edit > Project Settings and the frame range to 1-8.
 
7) View the AppendClip node and play through the sequence a few times.
 
8) Attach the Viewer to the first Crop node, and double click the node to open it's properties.
NOTE: Setting maxPanels to 1 will prevent you from accidentally seeing the box, or adjusting the properties, of another Crop node. 
 

 
9) Disable and enable the reformat knob on the Crop node.
 
10) Repeat steps 8 and 9 until the issue occurs.
 

 
Expected behaviour
The Crop node's box should always be in the correct position for the node being viewed and open in the Properties panel.
 
Actual behaviour
A Crop node's box will sometimes be displayed in the wrong position in the Viewer, when there is a downstream AppendClip node.
 
Workaround
Once the issue occurs, changing frame in the Viewer seems to update the box's position.
