Created attachment 355505 [details] File that exhibits the bug For some reason, the layout of the attached html file, with a `position: fixed` div followed by a `position: relative` span causes Safari to not notice if you change the contents of the span to another character of the same width. To reproduce: - Load the attached html file or use the link at the bottom of this post Expected result: The JavaScript should change the 一 to a 二 100ms after the page loads Actual result: The character is changed in the DOM, which you can see if you have the web inspector open, but the rendered character stays 一 until you either try to highlight character or resize the browser window.
