Front End Editing with Inline Text Fields

[thetuningspoon]

I'm trying out the front end features in earnest for the first time. I'm trying to edit my title field inline. It works, but for some reason it's allowing me to enter new lines for a single line text input. If I enter new lines and hit save, they are converted to <br /> tags (via the html entities output formatter). But if I double click to edit again, the tags are processed as live html in edit mode (potential security flaw?). And if I try to remove all of the new lines, I still end up with at least one stray <br /> tag at the end of the line.
