For content that is plaintext, currently it displays in the UI as a single line, continuing off the right edge of the box. I'm requesting that for these types of blocks, word-wrap it to within the window.

Also, when editing the plaintext content, the 2nd line is indented, which makes sense for code blocks, but not plaintext.

Thanks!
