no matter what I do, the <br/> element in it always gets removed, so it seems to me that I cannot search inside the address string.

I can't reproduce this (see the output in the [[]]s below), and you haven't said what your expected output is or what you mean by "search inside the address string" - see How do I post a question effectively? and Short, Self-Contained, Correct Example. As an example, I can replace the <br/> like so:

use warnings;
use strict;
use Mojo::DOM;
use Mojo::Util qw/trim/;

my $dom = Mojo::DOM->new(<<'HTML');
  <div class="address">
          <div class="icon"></div>
          <address>
            Sample Street 123<br/>45678 Randomcity          </address>
        </div>
HTML

my $addr = $dom->find('.address address')->first;
print "[[$addr]]\n";
$addr->find('br')->map('replace',"\n");
print "[", trim($addr->text), "]\n";

__END__

[[<address>
            Sample Street 123<br>45678 Randomcity          </address>]
+]
[Sample Street 123
45678 Randomcity]
