To work around this bug, store the Mojave installer on an external volume, such as a dmg or a USB drive. Thanks to @pudquick for discovering this workaround.

To be explicit about 'storing the Mojave installer on an external volume, such as a dmg', here's a oneliner:
sudo hdiutil create -fs HFS+ -srcfolder /Applications/Install\ macOS\ Mojave.app /tmp/Install_macOS_10.14.3-18D42.dmg
