Description of the bug

In the example below i am polling a remote image every second:

(defpoll mediaart 
  :interval "1s"
  `ruby ~/.config/hypr/UserScripts/MediaWidget.rb --arturl`
)

(defwindow media
  :geometry (geometry :anchor "bottom left" :width "300px" :height "330px" :x "30px")
  (box :orientation "v" 
    (box  :height "300px" :style "background-image:url('${mediaart}')" :class "mediaart")
  )
)

This works but if for any reason the internet is disconnected, the widget just freezes. Killing eww will remove all other widgets or layers as expected but this frozen widget will persist. Restarting eww and re-showing the widget will just draw a new instance of the widget over the frozen one.
