Icon-button - in the outline version the border sinks behind parent background due to stacking context

[desig9stein]

Description

The outline version of the icon button is created using an ::after pseudo-element, which adds a border around the button. This element is assigned a z-index: -1, but this causes an issue when the button is placed within an element that has a background color.
Due to the stacking context, the border is rendered behind the direct parent element's background since the button itself does not have a z-index.

Fix:
If the z-index: -1 on the ::after element is not necessary remove it or if it's required add z-index: 0 to the button itself
