Thanks for your quick answer Nik!
It happens when I press shift-enter one time at the end of an editable piece of content (p,h1,h2,etc).
The HTML becomes like this:
<h1>Lorem Ipsum<br></h1><p>dolor sit amet, consectetuer adipiscing elit. </p>
Which looks like this in the editor:
Lorem Ipsum
dolor sit amet, consectetuer adipiscing elit.
*But this:*
Lorem Ipsum
dolor sit amet, consectetuer adipiscing elit.
when the editor is closed. When the editor is opened back up, the return pops back up as well.
Also one more question: is there any way to insert images in the same region as text i.e. surrounded by text?
Thanks a lot!
