popup_light can only change color temp but not rgb color

[brvn0]

Describe the bug
When using popup_light with card_light, I can (on multiple devices: win + android) only change the color temperature and not the rgb color. When trying to tap anywhere on the color circle it will just reset to the previous location. The color is correctly displayed in the circle when changing the color via the homeassistant settings menu.

To Reproduce
create a card_light card and hold it, then try setting the rgb color
i installed browser_mod as well and put the corresponding entry in my config (browser_mod:)

Screenshots

Related Logs (can be found in the browser-console (F12))
this is a card_mod warning i receive when opening the popup but it only seems to talk about a deprecation notice and nothing concerning the actual problem

You are using a custom card which relies on card-mod, and uses an outdated signature for applyToElement.
The outdated signature will be removed at some point in the future. Hopefully the developer of your card will have updated their card by then.
The card used card-mod to apply styles here: <browser-mod-popup card="true">

Additional contex
the light is a rgbw (warm + cold white) light with tasmota installed, setup via the mqtt integration and it works completly with the default homeassistant ui/ by setting color in the settings menu
