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)
