ID 561182 - Soft effects/SubtrackItems don't always update their color on the timeline until the timeline is active or given focus

Problem summary
Soft effects/SubtrackItems don't always update their color on the timeline until the timeline is active or given focus.
 
Customer reported version
Hiero 14.0v2
 
Customer reported platform
CentOS 7
 
Steps to reproduce
1) In Nuke Studio/Hiero, import any footage and add it to the timeline.
2) Right-click the clip on the timeline and add a soft effect, such as a Grade node.
3) Open the Script Editor tab, then run the following code snippet:

for vTrack in hiero.ui.activeSequence().videoTracks():     for items in vTrack.subTrackItems():         for effect in items:             effect.node()["tile_color"].setValue(4288086783)

4) Observe the changes made to the soft effect in the Properties bin.
5) Click anywhere in the timeline and observe any changes.
 

 
Expected behavior
The soft effect color should update and change when running the Python command including the tile_color knob.
 
Actual behavior
The color of tile_color does not update until giving focus to the Timeline by clicking the mouse in the Sequence.
 
Workaround
There is no available workaround at this time.
