Completion doesn't work if cursor is not at the end of the word

Project is parsed successfully, but if I place cursor in the middle of some name and press autocompletion - the list is wrong.

Start by locating the completion-handling entry point in the Kotlin language server and reproduce the issue with the cursor inside a name rather than at its end. Compare the completion results for both cursor positions. Done means completion returns the expected list when the cursor is in the middle of a name; the issue names no specific file or test.
