eDefTagDialog go nuts in node/*/edit preview, and comment posting pages.

It seems that the content div above the textarea interferes with the eDefTagDialog. I tested with the "Insert/edit link" button:

1. The dialog box will be filled with "undefined" cells (PNG as attached)
2. The generated a_href code dumps out some odd functions (below)

<a href="test_link" title="test_title" each="function (iterator) {
    var index = 0;
    try {
        this._each(function (value) {try {iterator(value, index++);} catch (e) {if (e != $continue) {throw e;}}});
    } catch (e) {
        if (e != $break) {
            throw e;
        }
    }
    return this;
}" eachSlice="function (number, iterator) {
    var index = - number, slices = [], array = this.toArray();
    while ((index += number) < array.length) {
        slices.push(array.slice(index, index + number));
    }
    return slices.map(iterator);

I applied some stop-gap fixes (below). I don't think I have located the root cause but just to avoid inserting the odd functions to the dialog box and the generated code.

I ain't sure whether this is specific to my site (as I have installed quite a number of additional modules), or generic to also a bare-bone Drupal 5.1.

Many thks,
