Not sure whether it is a duplicate of bug 106272, but quite similar.
Reproduced in Kubuntu 18.04 with fcitx. 版本：6.2.0.0.beta1+ 組建 ID：6ab7bfbca4148416233dbf8b9bfc79f3a1dfa821 CPU 執行緒：2; OS：Linux 4.15; UI 算繪：預設; VCL: gtk3; TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:libreoffice-6-2, Time: 2018-11-27_19:54:44 語言地區：zh-TW (zh_TW.UTF-8); UI-Language: zh-TW Calc: threaded Kubuntu 18.04 with other input method engine (my case "gcin") would not reproduce this problem.
the IM looks for surrounding_text, the a11y apis are used to try and find the widget which has focus, ends up searching the spreadsheet grid for the cell, the virtual grid is immense so its searches for years
