Created attachment 8372585 [details] test-firefox.html User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release) Build ID: 20140127194636 Steps to reproduce: Requirements: * <select>-box with at least 21 <option>'s (which means that the <select> gets a vertical scroll bar – at least under Windows) * 'onclick' eventhandler on the <option>'s (not the <select>!) * The user needs to have the <select> positioned near the very bottom of the browser window, thereby forcing the <select> box (when opened) to expand towards the top, not towards the bottom * The user needs to open the <select> by clicking on the text (of the initially shown <option>), not on the arrow-symbol at the right corner of the <select> Actual results: 'onclick' fires at the last <option>; although the user clicked on no <option> at all (just opened the <select>) or (debatable) on the first <option>. Expected results: 'onlick' should not fire.
