Javascript("element.append()") looks broken.

So something like

Javascript("element.append($('<a href=\"#\">Link</a>'))")

Creates a link that is flushed to the right due to the flex hbox. Appending to toinsert works as I would expect. Not sure if element referring to output_area is a bug or API change since it was explicitly done here 0ea988b

I don't think this change was necessarily intentional. I can't see a good reason why this was changed (probably for code consistency across append methods, since none of the other methods expose APIs based on their internal variable names).
