To deal with deeply nested fieldsets on larger forms, I have added an oscillating odd/even CSS class to tags in my Seven subtheme by overriding theme_fieldset and updating the CSS selectors. IMO, this is an improvement over the current theming of relying solely upon gray borders and a single change to #f8f8f8 at the 3rd level of nesting.
I also slightly tweaked the non-white fieldset background color from #f8f8f8 to #f7f7f3 to better match the Seven header.
Can this change be added to the Seven theme in Drupal core?
Needs work
1.0
Code
The change alters the user interface, so before and after screenshots should be added to document the UI change. Make sure to capture the relevant region only. Use a tool such as Aviary on Windows or Skitch on Mac OS X.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Since seven has been removed from D10 I'll move to the contrib
Don't believe any theme in D10 is currently having this issue.
I have check the according to issue branch its properly updated the D10 version no need to reroll the patch and branch files.
If have any doubt and I am missing something please let me know.
Thanks
