Groups broken

[koppor]

I have "Float marked entries" active and I expect (i) entries belonging to a group float to the top and (ii) when changing a group that the selection updates.

What happens:

1. Click on "All Entries": No marking. OK
2. Click on a group: Some entries white, some gray. The currently selected entry displayed in the middle. OK
3. Click on another group 2: Nothing changes. If I start scrolling, the table updates and is displayed as follows:

Not OK. I expect the found entries to float to top:

This display can be achieved if I click on "All Entries" and then on group 2.
