Native / better styleable context menus on Linux?

[Koli]

MacOS and Windows 11 recently got their native context menus with their respective transparent blurred surfaces. On linux, it doesn't seem to be doable from userChrome CSS (transparency is there, but blur is not picked up), and while there is an about:config flag for native GTK context menus, on my machine it's a mess, being a list of every possible option in a context menu. I'm running on KDE and all I'd want is Firefox to stick out less from my system.
