how do i limit kate's auto-complete to only words already in the document?

that’s how it worked in the last couple distros i tried but now on kubuntu it shows all kinds of (unhelpful) words. i tried disabling “keyword completion” but it did not change this behavior. thanks for reading! edit: here is what it says under “components” in the “about” section: Kate: 25.08.1 KDE Frameworks: 6.17.0 Qt: Using 6.9.2 and built against 6.9.2 Ubuntu 25.10 (Wayland) Build ABI: x86_64-little_endian-lp64 Kernel: linux 6.17.0-14-generic edit2: i tried upgrading kate to the latest (beta?) version 25.12.2 but now it’s not even launching…
