Install/update inconsistency

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).
OS version and name: 4.19.102-1-MANJARO
Poetry version: 1.0.3

Issue

I have single library dependency in pyproject.toml - google-cloud-ndb==1.0.1.
When I run poetry install in a fresh project, everything goes well: library is installed and I can import/use it as usual.
However, when I do poetry update right after poetry install, poetry removes grpcio.
That could be a systematic bug in dependency resolution (note that grpcio is marked as extra dependency for several packages: googleapis-common-protos, google-cloud-core, google-api-core).
To my understanding, updating a few seconds after fresh install should not do anything.

Follow these steps:

$ mkdir poetry_update_bug

$ cd poetry_update_bug

$ echo '
[tool.poetry]
name = "poetry_update_bug"
version = "0.1.0"
description = "Help reproduce install/update bug"
authors = ["Sergi Chalauri <sergi.chalauri@gmail.com>"]

[tool.poetry.dependencies]
python = "^3.8"
google-cloud-ndb = "1.0.1"

[tool.poetry.dev-dependencies]
# None needed

[build-system]
requires = ["poetry==1.0.3"]
build-backend = "poetry.masonry.api"
' > pyproject.toml


$ poetry install -vvv
