Various editable parts of LibreOffice do not support AccessibleEditableText even though they are editable. Since LO advertises support for system call "delete surrounding text" these editable areas missing the implementation are not properly handled by input methods like ibus-kmfl. -writer comments: sw/source/uibase/docvw/SidebarTxtControlAcc.cxx? -draw comments: sd/source/core/annotations/Annotation.cxx? -draw tables: svx/source/table/accessibletableshape.cxx? -math: starmath/source/edit.cxx? (see Bug 91641 for details about ibus/kmfl setup to replicate the problem of having composing characters (like ";n" not being swallowed up when creating "ŋ".)
draw tables already are AccessibleEditable. The problem was related to initial focus, and being able to switch focus when moving between the different cells. See bug 96685. See https://gerrit.libreoffice.org/#/c/21046/ for a proposed fix for Writer Comments.
I trust your assessment, and am thus setting this to NEW. However, since it's not really a meta bug (in the sense that it isn't a common collective report for many separate bug reports), removing the tag.

Hello Aron, Could you provide a steps-by-steps description for this bug ? I don't understand the user consequence of this bug. Best regards.

Hi Alex, Justin is a long-time LibreOffice developer, and this seemed to be an issue described on a level that is closer to devs, I trusted his expertise, and didn't bother actually reproducing it. My understanding is that this is related to the feature that is described in the last sentence in the description. With some input systems special characters can be composed using multiple simple characters (eg. can be typed with keyboard), and then the combinations are replaced with the respective special character. For this certain UI components has to support specific calls ("delete surrounding text") that is apparently missing.

(In reply to Justin L from comment #0) > -math: starmath/source/edit.cxx? Well, imagine that. It looks like this was fixed in 5.2, from author Justin Luth on 2016-03-09 16:49:52 +0000 commit 598e6a024163f1510d076000788b7745625f5ed5 tdf#96685 - ensure FindFocus a11y context is valid EditableText At least, that is my guess. A bibisect pointed to the range of https://cgit.freedesktop.org/libreoffice/core/log/?id=67c8049a3abcaf9aa692fc9ba768b5db9fbb2f05&qt=range&q=45701913f642b17aabd67b52de9002cc79cf07ae..3a8844752c22e18d27aa310ae859f8cb660865b9&ofs=50
(In reply to Justin L from comment #0) > -writer comments: sw/source/uibase/docvw/SidebarTxtControlAcc.cxx? Fixed in 7.1, but hard to pinpoint exactly which commit in bibisect it is. git checkout xyz isn't consistent, so somehow certain libraries must not be reloading or refreshing. Anyway, my best guess would be that it is fixed by author Caolán McNamara on 2020-10-25 22:02:17 +0100 commit ce5e41ab99af350ca8f4b9fef3017d53f3526f83 Related: tdf#137620 use existing SalEvent::SurroundingTextRequest for signalIMRetrieveSurrounding
