12353 Markup inserted prior to doctype not handled nicely. Marcus Bointon "Any HTML markup inserted before a `doctype` or `` tag is clearly invalid, but the way that CKEditor handles it isn't helpful. Given a doc that starts like this (adapted from your [http://ckeditor.com/demo#full-page full-page demo page]):
{{{
hello
CKEditor Full Page Example
![]()
Apollo 11
...
}}}
It is transformed into this:
{{{
hello
CKEditor Full Page Example
![]()
Apollo 11
}}}
If you pass this into any HTML sanitisation system (such as htmlpurifier), it will probably strip everything after the closing `` (trashing nearly all of the document, including all of the original `head` tag), and renderers may ignore anything after the ``, though I note that CKEditor does not. I understand the reasoning behind this approach, but it is unlikely that is what the user intended, and it would be better to try something a little more sane first, for example, if there is a `` tag, move the early markup after that, so the output would become:
{{{
CKEditor Full Page Example
hello
![]()
Apollo 11
...
}}}
If that fails, //then// fall back to wrapping it in an HTML element. As it stands, moving all the content to after the `` tag is far more destructive than having content before the `` tag in the first place!" Bug confirmed Normal General 4.0
