+Feature: Ensure that a comment remains visible if its popup menu is open
+  In order to insert quick list comments in the PDF editor
+  As a teacher
+  I need the comment to stay visible when its popup menu is open
+
+  Background:
+    Given ghostscript is installed
+    And the following "courses" exist:
+      | fullname | shortname | category | groupmode |
+      | Course 1 | C1 | 0 | 1 |
+    And the following "users" exist:
+      | username | firstname | lastname | email |
+      | teacher1 | Teacher | 1 | teacher1@example.com |
+      | student1 | Student | 1 | student1@example.com |
+    And the following "course enrolments" exist:
+      | user | course | role |
+      | teacher1 | C1 | editingteacher |
+      | student1 | C1 | student |
+    And I log in as "teacher1"
+    And I am on "Course 1" course homepage with editing mode on
+    And I add a "Assignment" to section "1" and I fill the form with:
+      | Assignment name | Test assignment name |
+      | Description | Submit your PDF file |
+      | assignsubmission_file_enabled | 1 |
+      | assignfeedback_editpdf_enabled | 1 |
+      | Maximum number of uploaded files  | 1 |
+    And I log out
+    And I log in as "student1"
+    And I am on "Course 1" course homepage
+    And I follow "Test assignment name"
+    And I press "Add submission"
+    And I upload "mod/assign/feedback/editpdf/tests/fixtures/submission.pdf" file to "File submissions" filemanager
+    And I press "Save changes"
+    And I should see "Submitted for grading"
+    And I should see "submission.pdf"
+    And I should see "Not graded"
+    And I log out
+    And I log in as "teacher1"
+    And I am on "Course 1" course homepage
+    And I follow "Test assignment name"
+    And I navigate to "View all submissions" in current page administration
+    And I click on "Grade" "link" in the "Submitted for grading" "table_row"
+    And I wait for the complete PDF to load
+
+  Scenario: Add an empty comment and open its menu
+    When I click on ".commentbutton" "css_element"
+    And I draw on the pdf
+    And I click on ".commentdrawable a" "css_element"
+    Then ".drawingcanvas .commentdrawable" "css_element" should exist
+
+  Scenario: Add text to a comment and open its menu
+    When I click on ".commentbutton" "css_element"
+    And I draw on the pdf
+    And I set the field with xpath "//div[@class='commentdrawable']//textarea" to "Comment"
+    And I click on ".commentdrawable a" "css_element"
+    Then ".drawingcanvas .commentdrawable" "css_element" should exist
+    And the "class" attribute of ".drawingcanvas .commentdrawable" "css_element" should not contain "commentcollapsed"
