Difficulties in obtaining IDs in links

This is an excellent module. Thanks to developers.

I have a problem and I need some help.

As required by another module (see here), I need to insert IDs in a few links, ie, some links need to have this format:

<a href="node/100" id="webform-popup">Link</a>

I'm trying, but I haven't succeeded yet. What I did:

After I install and enable as usual the version 6.x-1.x-dev of the module, I set up for use only by authenticated users, who will use Full HTML.

On the edit page of the Full HTML input format, I disabled the HTML Filter and I enabled the Wysiwyg Filter.

On the module's configuration, I enabled the following elements and attributes:

a[!href|id|],

In Rules for Element IDs, I inserted the element webform-popup.

The filters that are in use, have been rearranged in the following order:

- WYSIWYG Filter
- Disable Lightbox iframe filter
- Lightbox filter
- Lightbox G2 filter
- Lightbox slideshow filter
- Lightbox iframe filter
- Lightbox video filter
- Lightbox modal filter
- HTML corrector
- Transliteration
- CKEditor Link Filter
- Line break converter
- Pathologic
- URL filter
- Emogrifier

I believe that with these settings, the IDs should be entered on the links, but not what is happening.

What am I doing wrong? Can anyone help me?

Now, thanks.
