Research direction
Start in FtpServerFragment.kt at getMainActivity (line 124), then trace changeFTPServerPort (line 819) and the onOptionsItemSelected callback (line 210) shown in the stack trace. Determine how the dialog action can run after the fragment is detached; done means the same lifecycle path no longer raises the IllegalStateException.
