ID 472228 - Concatentation breaks the bounding box when using large scaling with Transform nodes.

Problem summary
Concatentation breaks the bounding box when using large scaling with Transform nodes.

Customer reported version
nuke.13.0v1

Customer reported platform
windows10

Steps to reproduce

1) In Nuke, create a Noise node and add a Transform node.

2) In the Transform node properties bin, set the Scale knob to 10.

3) Add a Merge node, and attach a Checkerboard with a Reformat node.

4) In the Reformat node properties, enable the black outside and preserve bounding box knobs.

5) Add another Transform node downstream of the Merge node, to be shown as follows:

set cut_paste_input [stack 0]version 13.0 v1CheckerBoard2 { inputs 0 name CheckerBoard2 selected true xpos 1915 ypos -66}Reformat { black_outside true pbb true name Reformat1 selected true xpos 1915 ypos 6}Dot { name Dot2 selected true xpos 1949 ypos 84}push $cut_paste_inputNoise { center {1024 778} name Noise1 selected true xpos 1803 ypos -56}Transform { scale 10 center {1024 778} name Transform1 selected true xpos 1803 ypos 13}Merge2 { inputs 2 name Merge1 selected true xpos 1803 ypos 81}Transform { scale 0.05 center {1024 778} name Transform2 selected true xpos 1803 ypos 149}​

6) Adjust the second Transform node Scale to .05, viewing the bounding box in the Viewer.

Expected behavior
The bounding box should remain the same with or without the Merge node.

Actual behavior
The bounding box is larger than the merged items.

Workaround
Unknown. If known please add steps to workaround or avoid the problem
