Group no longer selected and focused when groups filter is deleted

1. Open a large JabRef database with several (explicit) groups
2. Use the groups filter to find a group of your choice
3. Select that group - it should be marked in blue
4. Remove the filter, i. e. delete your search term in the groups filter field
5. The group that you originally selected is no longer marked in blue/selected. Instead, another (random?) group is selected/marked in blue. The groups panel is also no longer focused/centred on the groups that you originally had selected/marked in blue.
6. This is inconvenient, if you want to filter for a certain group but also want to check its subgroups, after you filtered for the group. The current implementation allows you to quickly filter for the group, but the way the filtered group is displayed currently, excludes potential subgroups of the filtered group. To see the subgroups you either have to explicitly filter for them (i. e., also remember their name) or scroll to the actual group without any filter being applied. It would be nice if JabRef could remember the group you filtered for and that has been marked in blue and keep the groups panel centered on that group, when you delete your filter keyword.

Maybe the following is also related to this issue (I am on the latest daily build on 2018-03-23):

1. Select an entry and right click to add to a group.
2. When the entry is added to the group, the entry is no longer selected and focused.

It occurs only in recent builds for the month. I hope this has the same root cause as the OP's issue.

The issues persists in the latest developer version of JabRef. The only change to the original issue description appears that instead of selecting/marking in blue another random group, now always the All entries group is selected, when the filter is removed.
