"Two-Pane Calendar" example test puts IE 8.0 into Compatibility View

[reid]

The automated tests for the example "Two-Pane Calendar with Custom Rendering and Multiple Selection" cause IE 8.0 to automatically switch to Compatibility View. This causes the browser to act like IE 7.0.

This test should not put the browser into Compatibility View.

This is causing problems for Selenium — the switch to Compatibility View causes the browser to restart. This also causes problems for Yeti — the switch causes the browser to report it's IE 7.0 which halts testing.

Steps to Reproduce

1. cd yui3/src/calendar
2. yogi serve
3. Navigate IE 8.0 to the Two-Pane Calendar example at http://127.0.0.1:5000/docs/calendar/calendar-multipane.html

Tested on IE 8.0 on Windows 7.
