[Sidebar] does not toggle correctly with Semantic UI RTL build

Hi, Using a sidebar with an RTL build, when it opens, it uses double the space on the right side and when it closes it leaves a visible area on the left side of screen and messes up the elements on the page. I could not use the fiddle as instructed in guidelines because it is a ltr version and could not find a cdn for rtl version to setup another fiddle so I uploaded the files to my server for testing and reproducing the problem. http://behnood.darjade.ir/sidebar.html it is a ui inverted vertical menu sidebar that is toggle by a ui labeled icon button. I removed all other html and css and js to make sure nothing is interfering with this.
