Question
Why does the <link….> tag create odd looking HTML source code?
Answer
This is an intentional design in the TinyMCE WYSIWYG tool. It forms an HTML document by creating an IFRAME and a pseudo-document complete with its own <html> and <link> Because of this, the tool removes the <link> tag or any <head> tags entered in the code.
This issue does not exist with the CKEditor added in v8.2
