felgall,
PM was disabled. The normalizeAll function code located at
http://javascriptexample.net/dom36.php
has unballanced parentheses in the first conditional. Maybe a type-0?
The conditional in question is repeated below for clarity:
Code:
if((3 === c.nodeType && !/\S/.test(c.nodeValue))) || 8 === c.nodeType) {
node.removeChild(child);
}
