No, it wasn't, but indeed, there was a missing ingredient.  I had
forgotten to set tab-always-indent to 'complete.

With this recipe, I can reproduce the bug:

   $ emacs -Q -f package-initialize -L ~/path/to/eglot/eglot -l eglot  \
     ~/path/to/a/python/file.py                                        \
     --eval '(setq tab-always-indent (quote complete))' -f eglot

Don't know what's up, though.  Going to have a better look.

João
