Won't fix
The issue happens in the following case:
When the Divi theme is active the custom CSS from the View listing posts is also loaded. This happens even when if the View doesn’t display the post content (body).
This issue can’t be fixed from the Toolset side because some themes apply the_content filter on the excerpt which doesn’t follow the WordPress standards.
To avoid this issue please be more specific with the CSS you add.
For example, instead of adding the following CSS:
.my-css-rule { // this will be applied to the search-results page }
You can use something like this:
body.single .my-css-rule { // this won't be applied to the search-results page but only to the single page }
