Scale :value locks at 99 even if :max goes beyond? Bug?

[LurkAndLoiter]

(scale
  :class "media-scroller ${player.CanSeek == false ? "inactive" : "active"}"
  :round-digits 0
  :draw-value true
  :min 0 
  :max "${round(player.uDuration / 1000000,0)}" 
  :onchange "playerctl --player=${player.player} position {}"
  :value "${round(player.uPosition / 1000000,0)}") 

The scale bar max is seconds in song in this case 148. The value is the current playtime of the song in this case 106 however value locks in at 99. I can progress the song beyond 99 value with the onchange call. which leads me to believe this is a bug.

If this is the intended functionality I'd like to ask for assistance on the workaround below. The issue being reconverting the compressing timeline into a seconds value. See next block for workaround:

:max 99 
:onchange "playerctl --player=${player.player} position ${({} * (player.uDuration / 1000000) / 99)}"
:value "${round((99 / (player.uDuration / 1000000)) * (player.uPosition / 1000000),0)}"

Workaround:
..scripts/pushseek

#!/usr/bin/sh

playerctl --player=$1 position $((($2 * $3) / 99))

:max 99 
:onchange "~/.config/eww/scripts/pushseek ${player.player} {} ${round(player.uDuration / 1000000,0)}"
:value "${round((99 / (player.uDuration / 1000000)) * (player.uPosition / 1000000),0)}")
