Thanks Alastair for the additional information. The issue you report is likely different from the one this report was initially opened for, so if you believe you actually found a bug it would be better to file a new report.
However I tried to reproduce the issue you are reporting, but I can't. Here is the full transcript of the session, starting from a clean Bionic LXD container: https://paste.ubuntu.com/p/bDCv25xvsn/ I'm marking this report as Incomplete for now. If you think it should be discussed further please feel free to comment and then set the bug status back to New.
