Element Visibility Trigger doesn't work for CSS class


I want to use the Element Visibility trigger in Matomo 3.13. The configuration Selection Method: Element ID with the corresponding ID works fine but Selection Method: CSS Selector with the corresponding CSS class doesn’t work. Only the trigger of the first config appears in the debugger.

Is this a known issue or could be anything wrong with my config?

I found the issue myself. The CSS class has to be entered with a dot as prefix: .class
