Blank line added when using meta tag

[Roi Zaig]

If using a 'meta' tag in the html source and switching between source view and rendered view (not source view), a 'p' tag is added as follows:

Input source: <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" />

After to switching rendered view and switching back to source view: <p>

&nbsp;</p>

<p>

<meta content="text/html; charset=UTF-8" http-equiv="Content-Type" />

</p>

This creates an empty line at the top of the document.

Please use fullPage mode for that:
​http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.fullPage Meta tags can only be inserted in head section (​http://www.w3schools.com/tags/tag_meta.asp).

Nevertheless there shouldn't be any new paragraphs added when switching to source and back. I haven't found any duplicate so I’m confirming this ticket.

From CKEditor 3.0 till 3.0.2 meta tag was left untouched in paragraph (which allso seemed to me as good approach - ignoring == user friendly).

From CKEditor 3.1 till 3.5.3 rev. [6559] meta tag was removed from paragraph and pasted below it. Appart from that it was left untouched (which allso seemed to me as good approach - ignoring == user friendly).

From CKE 3.5.3 rev. [6561] to CKE 3.5.3 rev. [6628] meta tag was removed (which seemed correct as meta tags are not allowed in HTML4 in body (In HTML5 they are allowed as microdata) but such approach is not user friendly)

From CKE 3.5.3 rev [6629] meta tag gets wrapped in paragraphs and new empty paragraph is being added each time you switch modes.

Anyone using Wistia or other services to embed video using HTML5 "stuff" will have problems. Here is the code to embed one of our videos. When switching between views (or worse...when it loads from being saved previously), it closes the two initial divs early and puts everything after them. I hope this helps.

This is a duplicate of #8117. There's no reason to keep both, so I'm closing this one.
