I need to amend my description somewhat. It happens when on clicks at the very end of a line, but not always. For example, at
https://www.dokuwiki.org/features?do=edit&rev=0, clicks at the end of a line places the cursor at the beginning of the line. But a personal page with badbehavior, description, moderncontact and the theme Prsnl10 does not have this problem. Another page without any plugins or themes does.
