Open bracket in send_keys for select2 dropdown input results in option scroll down rather than text input

[gavk34]

When entering an open bracket into a select2 drop down the next option is highlighted rather than inputting the open bracket
watir-webdriver (0.8.0)

Firefox (41.0.1)

Sample Code

require 'watir-webdriver'
browser = Watir::Browser.new
browser.goto 'https://select2.github.io/examples.html'
browser.span(:class => 'select2-selection', :index => 1).when_present.click
browser.input(:class, 'select2-search__field').when_present.send_keys '('

This was created in the wrong project - should have been in watir-webdriver. My bad 😄
