Yup. There's a few other things with textboxes on this site. Journals especially. Enters/returns, slashes, quotemarks, a few other symbols might be broken. The "parapgraph" bits are also pretty broken.
there seems a text filter active that strips backslashes, since newline \n and carriage return \r contain back slashes (not really but in in filter notation), only rn is left when filtering paragraph ( \r\n )breaks...
