Commits navigation: old result sets displayed when going from a diff back to commits

Looks like it happens on Chrome (Version 24.0.1312.57 m). It doesn't happen on Firefox (15.0.1). Haven't checked others.

To replicate:

• Start with the browser on the commits page;
• Next I have the history modified - i.e., a new commit;
• Refresh the commits page - observe the new commit;
• Select a commit (any) to take you to its diff, etc.;
• Go back to the commits page;
• The result set is the old one (i.e., not showing the latest commit).

I find this rather difficult to explain so apologies in advance if it's not making sense. Happy to answer follow-up Q's.
