Miva - Remove Duplicate Current Breadcrumb from Empresa 5.21

1_breadcrumb-fix.md

1. Navigate to the "Smart Breadcrumbs" content tab
2. Place the following 2_breadcrumb-fix.xml contents above the breadcrumb foreach loop.
3. Update the page.

Note: When the Empresa 5.22 fix comes out this will not remove any breadcrumb links.

2_breadcrumb-fix.xml

<mvt:assign name="l.settings:breadcrumbs:count" value="miva_array_elements(l.settings:breadcrumbs:links)" />
<mvt:if expr="l.settings:breadcrumbs:count GT 1">
	<mvt:if expr="l.settings:breadcrumbs:links[l.settings:breadcrumbs:count]:code EQ l.settings:breadcrumbs:links[l.settings:breadcrumbs:count - 1]:code">
		<mvt:assign name="l.settings:breadcrumbs:duplicate_link" value="miva_array_pop(l.settings:breadcrumbs:links)"/>
	</mvt:if>
</mvt:if>

	<!--
		This is an example of where the fix could be placed.
		Anywhere above the foreach loop would work too.
