Color temperature is a circle in 2023.7.2

I just upgraded to 2023.7.2 and now when I click a light and then the color temperature button I am presented with this:

Why is that a circle instead of a slider as it was previously? What does the left-right axis represent? It makes no sense. Is it a bug or do I have to configure something?

Intended behaviour.


Its a circle so that it matches the colour selection so the left and right doesnt change anything for colour temperature.

It is just for consistency of design language i think.
