Tests:
Our ability to "edit around" content the HTML editing code does not yet handle very well.
For this test: Select and delete a table and some surrounding content.

Expected Results:
The content in the red box must exactly match the content in the green box (except for the border color).
For this test: Only selected content should get deleted. Surrounding content that is not selected should (obviously) not be affected.
