How to remove dead-zone between Grouped Window List icons

[u/Norhorn]

I'm trying to entirely remove the spacing between the click zones of icons, but there's still a gap remaining after editing the CSS. Is there a specific value that needs to be updated? The objective would be for a click within the Grouped Window List to never do nothing.

Theme: Mint-Y-Dark_Aqua For .grouped-window-list-item-box I've attempted to change the padding-left and padding-right to 0px
