Changing the file path and input transform of a clip via Python does not correctly update the colorspace in the Viewer.

Steps to reproduce
 
1) Open Nuke Studio.
 
2) Import a file (File > Import File(s)...) 
 
3) Double click the Bin item, to open its Properties and display it in the Viewer.
 
4) Run the following code in the Script Editor:

### a different image sequences, to the one currently in the project Binclip = "C:/_test_footage/frame_count.####.exr"   hiero.core.projects()[0].clips()[0].readNode()["file"].setValue(clip) hiero.core.projects()[0].clips()[0].readNode()["colorspace"].setValue("color_timing") ### set to some colorspace 

 
Expected behaviour
The value of the Input Transform knob should reflected in the Viewer. 
 
Actual behaviour
When updating the file path and input transform of a clip via Python, the value of the Input Transform knob is not reflected in the Viewer. The Thumbnail of the clip does appear to update though.
 
Workaround
You can use the refresh() function to force the update, however, this only seems to work when called inside a QTimer:

### a different image sequences, to the one currently in the project Bin clip = "C:/_test_footage/frame_count.####.exr"   hiero.core.projects()[0].clips()[0].readNode()["file"].setValue(clip) hiero.core.projects()[0].clips()[0].readNode()["colorspace"].setValue("color_timing") ### set to some colorspace ### workaround from PySide2.QtCore import QTimer QTimer.singleShot(100, lambda:hiero.core.projects()[0].clips()[0].refresh())
