Strange additional tab in suggestion management

Saving a suggestion without setting a status results in an additional tab that contains all of the suggestions.

To reproduce:

1) Create some suggestions with different statuses.
2) Go to the suggestion list view (suggestion/suggestion.pl)
3) In datatable, check one of the suggestions. 
4) Leave dropdown "Status" on "--Choose a status --"  and click "Submit"

Result: Edited suggestion is no longer visible in this tab. Suggestion list view gets a strange new tab with count of all suggestions as header and containing all of suggestions (including edited suggestion).

See attachment with screenshots.

What I would expect:

Some warning "Please choose a status"
or better
Update record without status change if a Reason but no status is given.
