Internet Explorer: clicking on each page tab results in warning messages in the console

1. Navigate to the Dashboard.
2. Click to go to Contacts Center page.
3. Click to go to Microblogs page.
4. Click to go to Messages page.

Actual result: With each click, there is a warning message in the console. This adds up to be a lot of ugly warning messages as you keep using SO and move around through it.

Expected result: There should be no warning when clicking any of the pages.
