Light Template Cannot Change Color Mode

[zolakt]

The problem

I want to create a template light, which will combine a relay switch (for on/off) and a led controller (for color temperature, brightness, color and effects).

Functionally everything works fine. However, once I try setting a color, the color_mode attribute gets permanently stuck at hs value. So, even when I change just the ww/cw temperature, the light does change the color correctly, but color_mode is still hs, and not color_temp as it should be. This results in the handle on the color temperature slider not being show, so you don't really know what is the current temperature. You can see it while you set it, but then it disappears after you leave it alone.

The color_mode does change as expected on the original led controller entity, but just not on the light template.

Attributes of the original led controller entity:

Attributes of the template light entity:

Expected behaviour: When set_temperature is called, the color_mode attribute should switch to color_temp.

I have the same issue. In my case I am using a mqtt light that is in xy color_mode.

This issue still exists. It hasn't been fixed in any update

I'm also having this issue with the latest 2024.6.1 version. Well, except I'm working with RGB instead of HS. I'm not very familiar with how these get fixed, but I see red crosses with "Review required" and "Merging is blocked". Does this mean it won't get fixed, or is this just normal procedure?
