<embed> getting converted to <ibed>

I had a heckuva time finding the solution to this, so I just wanted to re-post here.

Problem, embed tags get converted to ibed...

The problem is in tidyD(h) function:

remove this line: (line 381)

h=h.replace(/<(\/?)em([^>]*)>/gi, "<$1I$2>");

and add these two lines:

 h=h.replace(/<(\/?)em ([^>]*)>/gi, "<$1I $2>");
 h=h.replace(/<(\/?)em>/gi, "<$1I>");
