* fix for #3547

see https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty

because of "strict mode" - the `parentNode` property may not be writable and causes an error in `fakedom.js` (appendChild)

to reproduce: install CodeMirror, install "Tools for exploring internals of TW", open a heavy Tiddler like the Control-Panel in edit-mode, toggle preview on, switch to "parse tree" or "widget tree"

* check for tw fakedom
