Solar Forcast chart Render from State has a graphical Glitch

[spuky]

Describe the bug

If you open Solarforcast during the day the fill of the charts.js is drawing the closing line to the first datapoint in the chart.

This happens on opening the modal... as soon as new forcast state is pushed via the websocket the chart fixes it self... normal configuration with Control behavior 30s leads to an chart that fixes it self between 30 and 0 seconds because the incoming data from the web socket renders correctly

evccsolarforcastchart.webm

Observations:
in the past the chart grew with an animation when first data came in
Now the chart is rendered instant with opening...
changeing fill: form start to origin does not change the behavior....
