Nested selector with multiple groups aren't all prefixed with class name

[romdoq]

If one has a style defined in the following manner:

(defstyles my-style []
  {"th, td" {:border-width 0.1em}})

The nested selector will be expanded out to something like:

.my-app_css__my-style th, td

Which will apply the given style globally to all td elements. Rather, I would expect the resultant selector to have the base class name prepended to each selector group in the list, eg:

.my-app_css__my-style th, .my-app_css__my-style td
