custom css not loaded from custom template in dynamic bazar vue

I have a custom template for a form that load a css file. Displaying entries as list (and maybe other dynamic templates) doesn't load my custom css file so that my custom template is not correctly rendered.

## How to reproduce 

 - Create a form
 - Create a custom template for this form with `include_css(my/custom/css)`
 - Display list of entries for this form
