Hello,
I've an HTML Editor and if I write inside in Design Mode,
two lines, example :
HELLO <enter> HI
in html I've
<p>Hello</p>
<p>Hi</p>

If now in Design I select 'Hello' and I make it BOLD is ok, but if I put the cursor before 'Hello' and press the ENTER key also 'Hi' and all the contet of Html Editor becomes BOLD !
It seams that Editor adds wrong html code:

Thanks.
