If you put -- between <!-- and -->, the parsing isn't predictable.

Reproducible: Always

Steps to Reproduce:
a -- b -- <!-- c -- d --> -- e -- f<br/>
<b>a</b> -- <b>b</b> -- <!-- <b>c</b> -- <b>d</b> --> e -- f
Actual Results:  
Displayed:
a -- b -- b -- d --> e -- f

Copy to Clipboard:
a -- b --  -- e -- f
a -->b -- d --> e -- f

Expected Results:  
a b e f
a b e f

Verified.  Note that the parsing is in fact quite predictable if you actually read the HTML and SGML specs...

Oh, sorry :)

Other question: Why is copy to clipboard different?

Comment 4

[Henri Sivonen (:hsivonen)]

If you have set html5.enable to true, loading documents into a browsing context and parsing a clipboard paste go through different parsers (as an interim measure).
