a.list-group-item-actions do not behave correct with icon fonts

[nerdoc]

I think there are three issues with the list-group-item-actions.

1. if you have more than one icons, even svgs like in your preview, the link underline is visisble a bit, beween the icons:
   

you can test that on https://tabler.io/preview, right side, you have the actions in the list items, just open the browser's inspector and copy/paste another a.list-group-item-actions.

2. Another thing is that you are using svg icons in your preview. I don't want to use svg icons, but webfonts, as I use Django with no Js frontend. This looks terrible, as the underline is drawn here in full beauty:

I am using this code here: <i class="ti ti-{{ icon }} fs-2"></i>

I think in css there is missing something like a

a.list-group-item-actions:hover {
  text-decoration:none;
}

3. BTW - is the name "list-group-item-actions" a good one? wouldn't that sound better as list-group-item-action - because it is one, the plural form I would suspect to be as a class of a parent div. But changing this would be backwards incompatible - BUT: you are not 1.0.0 yet. it's beta20.

There may be a related problem - the same behaviour is seen in input-group.input-group-flat > input-group-text > a.link-secondary > svg /i.ti.ti-x
Your example in the preview, Form elements shows this with a svg icon:

When copied and with the X icon replaced by <i class="ti ti-x"></i>, it looks like this:

Again, mind the "link" style underline below the X - this is seen with all "icon" style fonts when used within buttons IMHO, be it action buttons or a.link-secondary

a.list-group-item-actions:hover,
.input-group-text  a:hover {
  text-decoration:none;
}

This is definitely not a solution, just a small workaround. But This should be fixed IMHO, as it renders icon fonts for some links in an ugly way.
