- Fix complex character input in Japanese, Chinese, etc. Was broken in getCursorOffset() in editor-expand.js. - Disable auto-scrolling in some edge cases when editor expanding is enabled. See #28328. Built from https://develop.svn.wordpress.org/trunk@29302 git-svn-id: http://core.svn.wordpress.org/trunk@29084 1a063a9b-81f0-0310-95a4-ce76da25c4cd
