[Overlay Plots] Removing 1 Object from the Elements Pool Removes 2 from the Legend

[rukmini-bose]

Summary

In an Overlay Plot, removing an object from the elements pool is removing two objects from the legend. The two are being removed are the selected object and another random one. Sometimes, refreshing can bring the legend back to the correct state.

Look at this image which was taken after removing an element. There are 7 elements in the legend, while there are 8 in the elements pool.

Expected vs Current Behavior

When you remove an object from the Elements Pool, we should see only that object being removed from the plot and the legend.

Steps to Reproduce

1. Navigate to an Overlay Plot that is populated with multiple data points.
2. Count the number of elements in the plot.
3. Go to Edit, and remove an object from the Elements Pool.
4. Now go to the legend, and count the number of elements that are in it.
5. Observe that there are 2 less elements in there, instead of 1.
