Send keys option is not working.

Hii Adams,

• We used your image(python2) to run the selenium test cases.
• image
• In single file, we wrote two test cases
  1: One with send keys,
  2: Another one without sending keys.
• The test case without using send keys is passed and another one with sending keys is failed.
• Test_case file link
• This is the final output

test_google_with_send_keys (testing.ExampleTests) ... ERROR
test_google_without_send_keys (testing.ExampleTests) ... ok

I got it working by replacing the line
chromium --no-sandbox $@ &
with
chromium --no-sandbox --headless $@ &
in the file
https://github.com/mark-adams/docker-chromium-xvfb/blob/master/images/base/xvfb-chromium

Hope that helps!
