Before, a code block would always end with a final newline. The newline was added unconditionally by `hide_lines`. When the code block is syntax highlighted by highlight.js, this is not a problem, no empty line is added for a final trailing `\n` character. However, when the code block is editable and thus handled by the ACE editor, a trailing newline _is_ significant. I believe this issue is most closely described by https://github.com/ajaxorg/ace/issues/2083 in the upstream repository. The effect of the way ACE handles newlines is that a code block like <pre> Some code </pre> will create an editor with _two_ lines, not just one. By trimming trailing whitespace, we ensure that we don’t accidentally create more lines in the ACE editor than necessary. |
