Weird simple_format behavior

I’m working on a page combining Ajax.InPlaceEditor and the
simple_format helper. The page is demonstrating some very strage
behavior. First, here is the code:

Bio:

<% if @user.bio %> <%= simple_format( @user.bio ) %>\ <% else %> No Bio Yet <% end %>
(click on your to bio edit it)

The InPlaceEditor works perfectly, but the page itself is what is
acting weird. Somehow on every refresh, an additional line break is
added to the final paragraph inside of the

so that the page
begins to rapidly expand. I can’t figure out how this is happening,
because it persists through both hard and soft refreshes without
being saved to the database.

Has anyone else experienced this strange behavior?

Thanks,
Josh
