URL looses query parameters after browser refresh

[goerch]

I'm running the rill example rill-app-engagement in rill developer and configure a pivot table. The URL shown in the browser bar is

http://localhost:9009/files/dashboards/mobile_events_explore.yaml?view=pivot&rows=country&cols=total_page_views&sort_by=&table_mode=nest

After refreshing the current page via the browser`s refresh button the URL shortens to

http://localhost:9009/files/dashboards/mobile_events_explore.yaml?view=pivot&rows=country&sort_by=&table_mode=nest

and I have to reconfigure the pivot table.

I expect to tbe able to store a bookmark to the original URL and reload the related page.

This happens at least with FireFox on MacOS with rill built from source today.
