It seems that background-attachment:local is not working on Safari 14.0.1 (macOS Big Sur) I tried on this demo from MDN https://interactive-examples.mdn.mozilla.net/pages/css/background-attachment.html for Safari 14.0.1, background-attachment:local and background-attachment:scroll are working the same. but it works right on Chrome (macOS Big Sur)

Created attachment 422372 [details] background-attachment: local not working See class css .strategy__data for the background-attachment: local. When scrolling horrizontly the background does not move.
