When I originally looked at that site WYSIWYG editor, the frontend looked nothing like the one we use; I think it's just a way newer version since we're on kentico 8.2 with this problematic instance. When I right clicked on it again, I noticed it was tagged with the same name as that one you posted.
Interestingly enough, I also didn't realize you could format
like that (not seen HTML or XML have that format for a tag before) and I thought it was a glitch. There's definitely something wrong with it in this instance, however; because I removed the / and space thinking it was an error, and it fixed the formatting issue (which I was originally tasked to fix, not the
<br />) on our staging environment.
anywhoo... appreciate ya a lot man!
