As the title says, spoiler tooltip remains visible ("Click to reveal or hide spoilers") in Chrome (tested in chrome) when a spoiler is open and you visit another tab and return to the original tab. Steps to reproduce: Visit this testing thread - http://xenforo.com/community/threads/testing-spoiler-bug.67278/ Open spoiler tag and do not click on any other part of the page. Keep the spoiler tab open. Click on a open tab/open a new tab in the browser. Return back to testing thread tab, you will see the tooltip visible. Click on any part of the page to remove the tooltip.
