crafting (and) JavaScript

Clone Behavior of <script> Tag

I wanted to scriptNode.cloneNode(true) and expected it to re-evaluate the JS of the node, but it didn't.

Each <script> element has a property flag called "already started".

This flag is already true, so a clone won't reevaluate the script. Solution: copy it manually.
