Ports seem to stay open when session is closed

[dbrody]

When opening browser via Playwright.BrowserType.launch(:chromium, options) and then closing the browser via Playwright.Browser.close(), the port opened to run chromium seems to stay open.

Seems to stem from within Playwright.Transport when called with Transport.Driver here:
https://github.com/geometerio/playwright-elixir/blob/17abee407e2d5fa30cc42ce62e8017c3d0ae8680/lib/playwright/transport/driver.ex#L18-L22

Even though all the GenServers are started with start_link it doesnt seem to clean up the port.

When closing the browser, playwright elixir keeps the GenServer of the Session alive.

In order to close the session and close the port you must close the session_pid like such:

# Start Browser
{_, browser} = Playwright.BrowserType.launch(:chromium, options)


# Close Browser and Port
DynamicSupervisor.terminate_child(Playwright.Channel.Session.Supervisor, browser.session)
