Short Description in List View doesn't show html

[[email protected]]

Hi,

we are using PS version 1.7.2.4 and Warehouse Theme,
we got html attributes in product short description and we would like to have it also in product list view.
At the moment we can see the short description but without html attributes ( <ul>, <li>, <img src="...">,)

 

We already saw some post about it but unfortunately not for our PS version.
We already tried to remove strip_tags:'UTF-8' in product-list.tpl but it doesn't work.

Does anyone know how to resolve it?
Thank you for your help
