Grafana 7.3.0 Dark mode panel

Just trying Grafana latest version 7.3.0.
Usually I used Dark mode in my dashboard, the value of the StatPanel always in white, Now, goes to Black.
Is it bug or new feature?
Is there any workaroud to make as previous version of the statpanel?

[Edit]
When I ise the threshold not using the default one, like below, the value goes back to white…
One more, when I choose the third little circle from the left, that I assume it’s the default color, the result back to black.
