When clicking a filter like "quarter" a URL parameter is added to the URL "&filter=quarter":
However, the navigation links at the bottom of the pane do not consider the existing filter. Note the absence of "&filter=quarter" in the link URLs:
Clicking these links loses the filter which either changes the result set or leads to a blank page since the pagination is based on the initial filter.
This is the case on all three tabs participation, voters, and editors.
It is possible to manually navigate to page two with the feature by adding the filter to the URL, e.g., Page 2 Quarterly Participation, so this is simply an issue with including the filter in the navigation links.
