#workspaces button.persistent not working in 0.10.0

[kingprawn22]

I've updated to 0.10.0 since it includes an update that hides the tray when there are no icons, which works well, but some functionality of my style.css looks to have changed. I have 4 persistent workspaces, and I want to apply a different style to those that are 'active' (have open windows), and those that are not. I have also tried the default style.css (renaming 'persistent-workspaces' to 'persistent_workspaces' to make it work), and can see the same issue there also, comparing between waybar 0.10.0 and 0.9.17 (Debian).

/* remove inheritance from GTK */
button:hover {
	box-shadow: none; /* Remove predefined box-shadow */
	text-shadow: none; /* Remove predefined text-shadow */
	background: none; /* Remove predefined background color (white) */
	transition: none; /* Disable predefined animations */
}

* {
	border: 0;
	border-radius: 0;
	font-family: "JetBrains Mono";
	font-size: 13px;
	font-weight: bold;
}

/* main waybar colors */
window#waybar {
	background-color: rgba(0, 0, 0, 0.3);
	color: #dedede;
}

/* gap on left side */
.modules-left {
	margin-left: 15px;
}

/* gap on right side */
.modules-right {
	margin-right: 15px;
}

#workspaces button {
	min-width: 20px;
	padding-left: 5px;
	padding-right: 5px;
	/* applies to 'active' workspaces */
	color: #dedede;
}

/* applies to all workspaces set as persistent */                 
#workspaces button.persistent {
        color: #555;
}

/* currently selected workspace */
#workspaces button.focused {
        background: rgba (0, 0, 0, 0.4);
        border-bottom: 2px solid rgba(255, 255, 255, 0.2);
}

/* when hovering over workspace button */
#workspaces button:hover {
	background: rgba (0, 0, 0, 0.2);
}

/* use a dash for module separated by slash in config
#custom-search {
	margin-right: 20px;
	border-bottom: 2px solid rgba(255, 255, 255, 0.2);
}*/

#pulseaudio {
	margin-right: 20px;
	border-bottom: 2px solid rgba(255, 255, 255, 0.2);
}

#cpu {
	margin-right: 20px;
	border-bottom: 2px solid rgba(255, 255, 255, 0.2);
}

#memory {
	margin-right: 20px;
	border-bottom: 2px solid rgba(255, 255, 255, 0.2);
}

Is there a new way to apply a style to 'active' workspace buttons? I've tried using the 'active', 'visible' and 'persistent' css things but none of them seem to have an effect. I even used 'empty' to instead apply a style to the empty workspaces, but again this made no difference.

Same issue here. It seems like everything was fine up until bb843e0 which completely broke persistent workspaces. It was mostly fixed in 7b3d155 but the styling no longer works.
