Trajectories between animations are not disposed properly

[ElDeveloper]

From @kwcantrell:

@ElDeveloper something odd seems to happen when playing two different animations. By that I mean first (on the emperor UI) select gradient=month and trajectory=trajectory. Play the animation. Then change gradient to day. The lines connecting the samples on the emperor plot jump around. The table shows the end of the animations. The images were taken from the linked .qzv.

Just playing day	showing day after month

Here is the console.
