User is not redirected to proper Homepage Tour stage when accessing the 'documentation' link on IE11

STEPS TO REPRODUCE

1. Open XWiki through an Incognito/Private Internet Explorer 11 browser instance
2. Click on the 'Next' button for each tour stage
3. On the last tour stage ('Tour Complete'), click on the 'documentation' link
4. Go back to XWiki instance by using the Back arrow/button from the browser

EXPECTED RESULTS

When returning from the 'documentation' link's page (http://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/), the last tour stage is displayed ('Tour Complete'), which contains the link previously accessed.

ACTUAL RESULTS

Only on IE11, the user is returned to the first tour stage ('Welcome to XWiki'). On Edge, Firefox and Chrome, the last tour stage is displayed, as expected.

The issue reproduces also on XWiki 9.11.7.
