Overview of the problem

Oruga version: [0.12.3]
Vuejs version: [3.5.26]
OS/Browser: macOS 15.7.1 / Chrome 143.0.7499.170

Description

The "clickable" prop of "Step-item" can be omitted, meaning its possible internal values are undefined/true/false.
When "clickable" is undefined, the behavior follows the description: "By default, previous steps are clickable while the others are not."
However, when "clickable" is explicitly set to false, the "Step-item" should always be unclickable. In practice, when "clickable" is "false", it can still be clicked when "item.value.index < parent.value.activeIndex".

Expected behavior

When clickable is explicitly set to false, the Step-item should always be unclickable.

Actual behavior

When clickable is false, it can still be clicked when item.value.index < parent.value.activeIndex.

Steps to reproduce

As stated above.
