Pull Request for Issue #46562 .

Summary of Changes

On line 86 of /modules/mod_breadcrumbs/src/Helper/BreadcrumbsHelper.php edited the value assigned to $item->link for the home page in the getHomeItem function:

$item->link = 'index.php?Itemid=' . $home->id;

the $item->link was ignoring some params in $home->link so that it results different from the Home link took from the Pathway.
In tmpl/default.php code, lines 33-38 check if there are duplicated entries

        // Get rid of duplicated entries on trail including home page when using multilanguage
        for ($i = 0; $i < $count; $i++) {
            if ($i === 1 && !empty($list[$i]->link) && !empty($list[$i - 1]->link) && $list[$i]->link === $list[$i - 1]->link) {
                unset($list[$i]);
            }
        }

looking also for duplicated home pages in a multilanguage site.
But with different ->link values the two Home links won't match, so they are both visible in the output.
