 Several "advanced" (or more appropriately, specific) HTML and CSS
 customizations inserted in the WordPress editor are removed when the post
 or paged is switched to visual editor view.

 This old post, [http://core.trac.wordpress.org/ticket/3311] , seems to be
 targeting a similar point, but I disagree with it, in that HTML shouldn't
 be added in the visual editor.  When HTML is added in the HTML editor,
 however, it should not disappear when the post edited using the to visual
 editor.

 For example, if there is an intro paragraph of plain text, followed by an
 iframe, flash embed, then table... the iframe, possibly flash, and table
 will all (rightfully so) need to be created with the HTML editor.  Say the
 administrator puts these enhancements on the page; another end user should
 be able to edit the paragraph of plain text in visual editor without the
 iframe, flash, and table being removed from the page.  While it would be
 understandable for the iframe etc. to be replaced with a (?) symbol of
 some kind in the backend, the code should remain in the HTML viewer, and
 therefore on the front end pages.

 HTML affected includes iframes, certain attributes like colspan in tables,
 various CSS markup, and pretty much anything that can't be accomplished
 using the visual editor.
