Manifest listing reorders itself at random when running composer commands

[iamsophiesk]

When running composer install for example, sometimes the packages in the manifest listing will reorder themselves. Where they may have been in alphabetical order previously, newly added or installed packages may instead sink to the bottom of the list.

This may be because it copies the structure of the composer.lock file (from a conversation with @joachim-n yesterday), but perhaps a forced sort would be useful?

Just thought I'd provide a supporting example:

I upgraded drush/drush on a feature branch, merged that branch into develop, then did git checkout develop && git pull followed by composer install.

That installed the packages correctly but resulted in this diff of my composer-manifest.yml file:
