Actually random "invalid session id" errors

[peaceful-james]

I am using the same version of chromedriver and chrome browser. I am using the default Chrome driver.

My setup is on docker and when I do this:

docker-compose down;
docker-compose up -d;
sleep 20; # in case it's some kind of "unreadiness" problem
docker-compose exec phoenix_app mix test test/wallaby/sanity_test.exs

then
sometimes the Wallaby test runs and
sometimes the Wallaby test errors with the invalid session id message.
It is random.

You can see from the way I am running the tests that nothing changes between different runs.

For my particular case, I have narrowed down where the random failures happen. It occurs (sometimes) when clicking checkboxes. Very very strange.

For posterity, I have same chromedriver and chromium versions (exactly the same - 83.0.4103.116)
