Drag and Drop of Blocks does not function when using Standard theme, in RTL mode

Add an RTL language package (Hebrew or Arabic or Farsi...) to Moodle (Home / ► Site administration / ► Language / ► Language packs) Switch to the RTL language you have installed by navigating to Moodle's Front-page and choosing it from the Language menu (or add "&lang=he" to the end of the URL you are currently using. If inside a course, set the RTL language from the course's setting) Navigate into any course Set Course theme setting to "Standard Theme" (Course setting >> Theme >> Standard) Turn Editing mode ON Move Blocks from right side to left side (btw, make sure Navigation and Settings blocks are on the right side column) Turn Editing OFF Make sure the blocks stay on the same position they were, when in Editing mode.
