[xmonad] Transparent borders are back

Many, many moons ago I tried to get the transparent borders I got around Sakura¹ windows to go away. I think the quest - with a lot of help - eventually succeeded back then (https://github.com/xmonad/xmonad/pull/59) Now they are back: Around Firefox 140.3.0esr's windows on Debian 13 (trixie) with xmonad 0.17.2: · https://koldfront.dk/misc/xmonad/firefox-xmonad.png I don't know where to start - has anyone seen/solved this?
