seen in beta labs as of Feb 27 and confirmed by testing against beta locally. After editing a page, no 'continue' button appears, which stops editing:
$ bundle exec cucumber features/diff.feature
@en.m.wikipedia.beta.wmflabs.org @test2.m.wikipedia.org
Feature: Page diff
Scenario: Added and removed content # features/diff.feature:4
Given I am logged into the mobile website # features/step_definitions/common_steps.rb:1
When I go to the "Diff test" page # features/step_definitions/common_steps.rb:92
And I click the edit button # features/step_definitions/editor_steps.rb:7
And I clear the editor # features/step_definitions/editor_steps.rb:23
And I type ABC DEF into the editor # features/step_definitions/common_article_steps.rb:10
And I click continue # features/step_definitions/common_article_steps.rb:41
timed out after 5 seconds, waiting for {:class=>"continue icon", :tag_name=>"button"} to become present (Watir::Wait::TimeoutError)
features/diff.feature:10:in `And I click continue'Version: unspecified
Severity: major
