[Bug]: no background for label-occupied in xworkspaces module resulting in weird visual bug

• [X] I have followed the debugging guide to narrow down the problem to a minimal config.

Steps to reproduce

I'm running polybar on Arch Linux with i3 and picom. Recently I've tried to redesign my config by making the bar transparent with the modules basically floating, but I've run into an issue with the xworkspaces module.

The label-occupied label doesn't have a background parameter, and instead it uses the background of the bar it was placed on. This creates a problem where if I want to have a transparent background, an occupied workspace will also have a transparent background, which I don't want.

This issue is partially solved by using format-background, but it results in this happening:

The occupied workspaces on the left have a normal background, but the ones on the right don't.

Minimal config

[colors]
background = #11111b00
background-alt = #31324f
module-bg = #1e1e2e
foreground = #cdd6f4
disabled = #7f849c
mauve = #cba6f7
green = #a6e3a1

[bar/workspaces]
background = ${colors.background}
bottom = false
width = 100%
module-margin = 0
modules-left = xworkspaces

[module/xworkspaces]
type = internal/xworkspaces

label-active = %name%
label-active-background = ${colors.background-alt}
label-active-underline = ${colors.mauve}
label-active-padding = 1

label-occupied = %name%
label-occupied-padding = 1

label-urgent = %name%
label-urgent-background = ${colors.alert}
label-urgent-padding = 1

label-empty = %name%
label-empty-foreground = ${colors.disabled}
label-empty-padding = 1

format-background = ${colors.module-bg}
format-foreground = ${colors.foreground}

[settings]
pseudo-transparency = true

nevermind, it wasnt specified in the docs that you can actually set a background for the label-occupied label, but it is possible
