ID 590312 - Sequence Viewers don't update when Clip/Shot Soft Effects are deleted or disabled/enabled

Problem summary:
Sequence Viewers don't update when Clip/Shot Soft Effects are deleted or disabled/enabled
 
Customer reported version:
Nuke Studio N/A
 
Customer reported platform:
N/A
 
Steps to reproduce:
1) Launch Nuke Studio, then navigate to File > Import File(s)... and select some footage.
2) Add the Clip to a new Sequence, then Right-Click and navigate to Open In > Timeline View
3) Create a Grade Soft Effect, and increase its gamma knob to a value like 5.
4) In the UI, move the Sequence Viewer so that it and the Clip Viewer are both visible.
5) On the Clip's Timeline, Disable/Enable the Grade Soft Effect or the Track it resides on, and observe how the Sequence Viewer does not update until its frame is changed:

 

Expected behavior:
Changing a Clip/Shot level Soft Effect's enabled state, or deleting it, should automatically update all Viewers displaying that Clip. 
 
Actual behavior:
Sequence Viewers do not accurately display the results of disabling/enabling or deleting Clip/Shot Soft Effects, until the current frame of the Sequence changes. In some previous versions of Nuke Studio, the Sequence Viewer would update as soon as it was given focus and it was not necessary to scrub to a different frame.
 
This issue also occurs when the Clip/Shot Soft Effects or their Tracks are disabled/enabled or deleted via Python:

seq = hiero.ui.activeSequence() timeline = hiero.ui.getTimelineEditor(seq) track_item = timeline.selection()[0] clip = track_item.source() for e in clip.effects():     e.setEnabled(False)
