I couldn't reproduce the problem anymore, in either Terminal or Konsole (both are CLI terminal emulators), so either it's gone or it's intermittent. We can treat this bug as closed unless and until I make a new version of this report. I don't know of a difference in circumstances unless it's that Fedora 32 Linux has had updates in between. Even though I don't recall an update being to either emulator, it's possible. Thanks.
