📚 Description

In the Responsive example, if there are fewer links than the itemsToDisplay value, the first breadcrumb is displayed twice.

Proposed solution:

We need to add an additional check in the remainingItems computed variable to handle this edge case.

+ const remainingItems = computed(() => items.value.slice(-Math.min(itemsToDisplay, items.value.length) + 1))
- const remainingItems = computed(() => items.value.slice(-itemsToDisplay + 1))
