xsize and ysize doesn't effect sliders in preferences

[Kia]

I noticed this odd behavior in slider styles, size parameters doesn't effect bars in preferences screen but other parameters work fine.
in this example:

Code: Select all

style slider_slider is gui_slider:
    xsize 100 left_bar "#fff"

the bar color changes but the size stays the same.
when I apply the size directly to the bar it works:

Code: Select all

bar value Preference("music volume") xsize 100

is there some miscommunication between styles and the bars?

still looking for a solution
