Launch Command

rofi -show drun

Steps to reproduce

rofi -show drun -theme-str '#element { text-transform: lowercase; }'

or

/* theme.rasi */
element {
   text-transform: lowercase;
}

What behaviour you see

A theme error of unexpected invalid property value.

What behaviour you expect to see

A list of entries that have a lowercase style applied to them.

I was surprised to see this old video (2015, 00:29:45) to somehow have lowercased elements.

I did notice text-transform does not seem to be supported, but is this perhaps possible in a different way?

The option drun-display-format seemed promising at first, but I did not manage to figure out how to pass lowercase text to that in the Pango markup language.
