The deleteCookie function in tiki-js.js uses an invalid date format which is not accepted by Internet Explorer (even version 11) for its expires attribute. As a result, the following line which is supposed to delete the cookie only sets its value to an empty string in Internet Explorer:
document.cookie = name + "=" + ((path) ? "; path=" + path : "") + ((domain) ? "; domain=" + domain : "") + "; expires=Thu, 01 Jan 1970 00:00:01 GMT";
This impacts code which checks for a cookie's existence, such as the following fragment from parse_first() (in parserlib.php):
$iconDisplayStyle = ''; if ($prefs['wiki_edit_icons_toggle'] == 'y' && ($prefs['wiki_edit_plugin'] == 'y' || $prefs['wiki_edit_section'] == 'y')) { if (!isset($_COOKIE['wiki_plugin_edit_view'])) { $iconDisplayStyle = ' style="display:none;"'; } }
The above example means that plugin call and section edit icons do not get their style set to display:none by specific CSS, which causes icons to show during load, until Javascript hides these when the page load is over. This happens when wiki_edit_icons_toggle is enabled and a user of Internet Explorer has hidden icons. To reproduce, it is probably necessary to display icons, then to hide them, then to load a page.
The invalid date format was introduced no later than 2003-08-07 and remains in trunk as of r68584.
