The navigation bar in TablePager and CodexTablePager correctly respects getDefaultQuery, adding those parameters to each link. However, the same is not done for the limit form. So, setting a different limit will lose all the default query parameters.
Not sure if there are examples of this in beta/prod, but it can be tested with the CampaignEvents extension, with an event with over 50 associated contributions, from
http://localhost:8080/w/index.php?limit=20&title=Special%3AEventDetails%2F{EVENTID}
Where using the limit selector will lose the tab parameter that controls the view.
