Insert element over selection breaks DOM

[Dinu]

Test:

• create 3x2 table
• select a number of cells
• insert image

The document trashed, going to source and back to wysiwyg will clean up the html, delete the image, and recreate what's left of the table.

On a side note, I need to do exactly this for a plugin, insert block elements, what's the place to ask about the ortodox way to manipulate the selection ranges?
