ID 610773 - Cat nodes don't trigger global callbacks in Nuke.

Problem summary
Cat nodes don't trigger global callbacks in Nuke.
 
Customer reported version
Nuke 16.0v1
 
Customer reported platform
Alma 9
 
Steps to reproduce
1) In Nuke, create a CopyCat node setup.
2) In the Script Editor, run the following code:
 

def check_cat_validation(*args, **kwargs):     nuke.tprint(f"{nuke.thisNode().name()} before Render!")     print(args) nuke.addBeforeRender(check_cat_validation)nuke.addBeforeFrameRender(check_cat_validation) 

3) Begin a render with the CopyCat node, observing the console before renders occur.
 

 
Expected behavior
The callback should be applied when renders occur. 
 
Actual behavior
The executed code is not evaluated. However, you can add the same function to the Python tab for the callbacks and it will work.
 
Workaround
There is no available workaround at this time.
