const jsxWhitespaceChars = " \n\r\t";
const matchJsxWhitespaceRegex = new RegExp("([" + jsxWhitespaceChars + "]+)");
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The problem is reported here

The location is miss leading, because there is no \n there.

Is it hard? I didn't read code, but I think strings are concated, lost original node info?

Another problem \n/\t/ should be escaped in message, they are invisible.

Or maybe we can just display the Regexp literal value in message.
