Description of the bug

In the following cases, current workspaces will not take effect. In order to solve this problem, label definition must be used.

(defpoll workspaces :interval "1s"
                    :initial "[]"
  "python ~/.config/eww/scripts/get-workspaces.py")

(defpoll current_workspace :interval "1s" :initial "1"
  "bash ~/.config/eww/scripts/get-current-workspace.sh")


(defwidget workspaces []
  (box :class "workspaces"
       :orientation "h"
       :space-evenly false
       :halign "start"
       :spacing 5
    (for workspace in workspaces
      (button :onclick "hyprctl dispatch workspace ${workspace.value}"
              :class "${workspace.id == current_workspace ? "current_workspace" : ""}"
        "${workspace.value}"))))

After startup, the current workspace cannot officially take effect unless the following configuration is added:

(label :text "${workspaces}${current_workspace}" :visible false)

Reproducing the issue

Just use the above configuration

Expected behaviour

The poll definition of current workspace should always start even without label! Because it may be referenced in the following judgments.

Additional context

Please read the description above

Hey, I could not reproduce the error of a poll not launching because there is no label. I tried the following:

(defpoll var :interval "1s"
                    :initial "0"
  "echo 1")

(defwindow button
  :monitor 0 
  (button :onclick "${var == 1 ? "eww close button" : ""}" "test"
	)
)

Also, to see whether the value updates:

(defpoll var :interval "1s"
                    :initial "0"
  "date +%S")

(defwindow button
  :monitor 0 
  (box
	(button :onclick "${var >= 30 ? "eww close button" : ""}" "test"
	)
  )
)

I also read the code that is launching inside of script_var_handlers.rs and polls are just launched no matter if they are used.

What happens if you try the examples I gave (didn't use your code because I don't have the get-workspaces.py)
