IE Selection Test Case for #8222

Steps to reproduce:

1. Without clicking inside the editor body, click the Find button - this will result in the first problem, H1 in the elements path and Paragraph Format combo
2. Cancel the dialog and Click Destroy
3. Click Create and open the Find dialog again as in step 1. - this time you get an error "getParentEditor().getSelection() is null or not an object
4. Repeat step 2 & 3.- span keeps getting added under the H1 element (inspect the H1 element to check)

Note:Once the above two issues are fixed, I believe the issue of the disappearing HEAD element will also get fixed
