I would suggest you try using ~ instead of $HOME in your alias:

  alias config='git --git-dir=~/.local/share/dotfiles --work-tree=~'

The tilde in ${~opt_args[--git-dir]}} ensures that tildes are expanded.
While using (e) is arguably the right thing to do, it will expand things
like command-substitution and we've always intentionally shied away
from expanding anything that could have side-effects when parsing the
command-line for completion.

The modifiers don't allow you to pick-and-choose expansions so there
isn't a trivial way to expand variable references without expanding more
problematic things.
