breaks formatting in views teaser and partial body

Issue Summary

If you have a large embedded inline media that you paste into a node body
and if that embedded media uses divs to format the display
and if you include that node in a view
and if that view display uses Node: Teaser or Node: Body (with the length limited) to display the field
and if the closing divs are not within what is included in the teaser or truncated body
Then
the closing divs are missing from the rendering and
subsequent rows or regions can be sucked into the unclosed div
and the formatting for the rest of the site is messed up

In particular, I found that this caused the blocks that are supposed to be in the righthand sidebar to be displayed at the end of a view at the bottom of the content area
