app.lvh.me took too long to respond - Capybara 3.40.0 (but works with 3.39.2)

Meta

Capybara Version: 3.39.2 -> OK
Capybara Version: 3.40.0 -> ERROR

Driver Information (and browser if relevant): selenium_chrome_headless

# spec/support/capybara.rb
Capybara.configure do |config|
  config.always_include_port = true
  config.javascript_driver = :selenium_chrome_headless
end

Capybara.app_host = "http://app.lvh.me:#{Capybara.server_port}"
Capybara.server = :puma, { Silent: true }
Capybara.default_max_wait_time = 5

Expected Behavior

The test succeeds.

Actual Behavior

Capybara::ElementNotFound:
       Unable to find css "#signin"

It's not found because the Rails App cannot load in the browser (app.lvh.me took too long to respond).

Steps to reproduce

The issue started after upgrading capybara from 3.39.2 to 3.40.0.

The test does not matter (I put one below for reference). The first test of my js: true test suite will always fail. The Rails app cannot load in the browser. If I save_and_open_page, I can see an HTML error page saying:

app.lvh.me took too long to respond

The following tests run normally. But they would fail with the same error if I ran them individually, one by one.

Very simple test:

visit new_user_session_path
within('#signin') do
  fill_in 'user_email', with: user.email
  fill_in 'user_password', with: user.password
  click_button 'Se connecter'
end

For now I downgraded to 3.39.2, but I would like to understand what happens to keep Capybara up to date.

Here's the HTML if I run save_and_open_page just before the within

This may be your environment not being compatible with the chrome --headless=new option. Register your own driver without that option and try that instead. Other than that look in your apps logs for any errors. Capybara just starts your app, it really doesn't have any control over how long your app takes to become accessible.
