How to prevent mce:protect after saving a template.

Hello!
Trying to insert into the template:

<a href="{{ organization.url|trim_slash }}/products/{{item.product.handle}}?product={{item.product_id}}&variant_id={{item.variant_id}}">
   {{ item.product.title }}
</a>

after saving we are getting:

<a href="&quot;&lt;!--mce:protected" 7b="" 20organization="" url="" 7ctrim_slash="" 20="" 7d="" products="" 20item="" product="" handle="" 3fproduct="" 3d="" product_id="" 26variant_id="" variant_id="" 22="" 3e="" title="" 7d--=""> </a>

Any suggestion on this>
