+Feature: Don't lose content when page or block is invalid
+  As a CMS user
+  I want to retain my unsaved content when a validation error occurs
+  So that I can fix the content and save it without recreating content
+
+  Background:
+    Given I add an extension "DNADesign\Elemental\Extensions\ElementalPageExtension" to the "Page" class
+      And a "page" "Blocks Page" with a "Alice's Block" content element with "original content" content
+      And the "group" "EDITOR" has permissions "Access to 'Pages' section"
+      And I am logged in as a member of "EDITOR" group
+
+  # The "unsaved changes" dialog causes errors unless this is tagged with "@unsavedChanges"
+  @unsavedChanges
+  Scenario: If a page is invalid, changes aren't lost
+    Given I add an extension "DNADesign\Elemental\Tests\Src\ValidationFailedExtension" to the "Page" class
+      And I go to "/admin/pages"

+    Then I should see a list of blocks
+      And I should see "Alice's Block"
+      And I should not see the ".element-editor-header__version-state--unsaved" element
+    When I click on the caret button for block 1
+      And I fill in "<p>New sample content</p>" for "Content" for block 1
+      And I fill in "Charlie's Block" for "Title" for block 1
+      And I press the "Save" button
+    Then I should see a "Validation error" error toast
