Basic UI: Text color depending of item string content

It doesn’t work. The code is not even saved. If I save it and refresh, the line is removed…

Neither work the code directly nor in the GUI:

In the meantime, I notice in the code editor a general issue but I can’t find the mistake.

Here the message:

But it seems be good. That is the code line 2 until line 9.

    Selection icon=presence item=FritzBoxStatus label="Betriebszustand"
    Group icon=sun item=Astronomische_Berechnungen label="aktuelle Sonnendaten" {
        Text icon=iconify:material-symbols:height item=Sonnenhoehe label="Höhe"
        Text icon=sun item=Sonnenrichtung label="Azimut"
        Selection icon=sun_clouds item=Tag label="Es ist gerade "
        Selection icon=sunrise item=Sunrise label="Sonnenaufgang"
        Selection icon=sunset item=Sunset label="Sonnenuntergang"
        Chart icon=line item=Sonnenhoehe label="Sonnenstand" period=12h refresh="1000000"
    }

In the previous version of OH (like 3.4.2) the code was without failures.
I hope the one has nothing to do with the other
