Big issue when change text's font and size

[James]

Even on Fckeditor demo site, the demo editor has same issue. For example, you can go to this url to copy all content into editor,

[url]​http://www.geierassetmanagement.com/new/geierassetmanagement/content.asp?contentid=401990464[/url]

then use "Ctrl-A" to select all content, then select one font or size from the editor, then you will see the title of page will go to bottom of page, all paragraphs are re-ordered. The content on the bottom of the page will go to the top of page. Sometimes, it even lose major content after you change font / size from the editor.

It is really a big issue since user can't change font / size by the editor. Your content's order will be changed by editor or you will lose some content after you select font / size from the editor

the url is:

​http://www.geierassetmanagement.com/new/geierassetmanagement/content.asp?contentid=401990464

That page has tags that are incorrectly nested, so the behavior is undefined given invalid input.

Reopen if you can provide a simplified testcase with valid HTML.
