For some reason there's two H1 elements on the page when I start editing it.

I can provide a screenshot.  I just clicked the "Edit" link and that's what I 
see.

I think that's beacause page|wikify_page|safe has its own H1.  Perhaps there 
needs to be a condition which would not display page.title|escape if there's a 
preview.

exactly.
I think first H1 specifies next block is preview better than simple title.
please review revision 45c244bb310d .

Don't you think this could disorient the user?

Example: I click the edit link and see two headers.  I think I did something 
wrong and delete one and save the page.  It has no header now.  I'm frustrated.

I changed to emphasize preview boundary.
How about this ?

I think it's OK.  There's a way to add custom CSS to customize the look, in 
case somebody doesn't like it.
