Modules pages refreshes when a section is clicked...

I used drush to create a new site & enable module filter.

On the website:
Click modules in the core admin toolbar.
Module filter comes up in the overlay.
Click a tab on the left, shows those modules.
Click another tab on the left, shows those modules, and now the browser acts like an outside link has been clicked and refreshes.

After the page refreshes..
Click another tab on the left, shows those modules, and now the browser acts like an outside link has been clicked and refreshes.

Plain annoying if you're trying to enable modules from multiple sections in one go.
... of course I just disabled overlay, but I didn't see this in the issues
