Can't save sequence name change

Scenario:

1. Click "Create sequence"
2. Paste any data, like "acgt", save sequence somewhere, set sequence name "Name 1" and check "Save file immediately".
3. Click on the sequence object name "Name 1", click F2 to rename, set the other name (e.g. "Name 2").
   Expected state: Sequence name marked with blue to show that some changes since the last saved version exists.
   Current state: Sequence name is black that means, that UGENE doesn't see any changes
