(separator) Below the separator is one entry for each named stylesheet link (if any). However there are some situations where "Basic Theme" is not needed and its existence is misleading. For example, when all of the linked stylesheets on the page are properly named and there are no inline styles, then "Basic Theme" has no purpose. Reproducible: Always Steps to Reproduce: 1. Go to sample site 2. Choose "Basic Theme" and then "No Theme" Actual Results: Shows both "Basic Theme" and "No Theme" above the separator Expected Results: Shows only "No Theme" above the separator "Basic Theme" is only needed when there is a stylesheet link without a name, or inline styles.
With the changes from fixing bug 253332 (No Style disables all CSS as well as any HTML-based styling with font tags, etc.), this situation should happen *very* rarely--i.e. only if the page has absolutely no styling at all. Marking WONTFIX. Thanks for the clear explanation in your bug report, though.
