Can't disconnect in manual transaction mode

[vitali.v.c]

Can't disconnect/invalidate connection in manual(non auto-commit) transaction mode in case if connection is lost:
App asks to rollback or commit transaction changes, and then hangs on "Disconnect from <dbname>: Rollback transaction". Only Emergency Exit helps in such situation.

Linux, x64, Oracle, DBeaver 1.5.2

Sometimes it happens with Oracle (not only) connections - JDBC driver just hangs on disconnect process. But it is rare situation. In most cases connection will be closed (maybe with warnings) even in case of network failure.
Do you catch this problem all the times? OR may be there is some very special use case to reproduce it?

Thanks!

PS Generally emergency exit was designed exactly for such situations.
