Clicking the color boxes for min, mid and max point of Degree Centrality does not update color gradient box

[seangrant82]

When you apply the color schema after you ran DegreeCentrality, if you go into the Rules based symbology, the color gradient selector does not update when you click the color in the minpoint, midpoint and maxpoint boxes.

Steps to reproduce:

1. Load a graph into Bloom
2. Open the Data Science pane and click Add Algorithm
3. Choose Degree Centrality then click Apply
4. Click Color Gradient in the bottom under Rules-based styling
5. Expand the Node and Relationship pane by clicking the expand arrow in the top right
6. Click on you node that has a blue circle on it indicating it has rules-based symbology
7. Click on any of the color boxes next to Minpoint, Midpoint or Maxpoint and you will see the position of the color pixel does not update in the big color gradient rectangle below them

As you can see, I have the Maxpoint selected but the color that is selected is from the Minpoint
