fix: right side panel visual indicators don't update for color picker… (#7489)

**Important code was mistakenly omitted in #7137, which caused this bug.
(@DrJKL )**

The color picker and node state components in the right side properties
panel have a visual indicator bug. While the components function
correctly and successfully change the node values, the visual state
indicators fail to update to reflect the current selection.
