IE11 vertical scrollbar covers the Menu icon

1. Open an instance of XE 7.4 using IE11.
2. Hover over the top right menu icon.

Actual result:

• A vertical scrollbar is displayed over a half side of the menu icon;
• Even if you change the zoom size of IE11, the issue persists;
• The menu is still clickable.

Expected result:

• I expect to see the scollbar of IE11 in the right side of the wiki page, without affecting the display of the menu icon.
