[webUI tests] stale element reference checking thumbnail in details panel

[phil-davis]

The following scenario, and similar ones that check the thumbnail in the details panel, sometimes fail:

  Scenario: the recipient user should be able to view different areas of details panel in Shared with you page # /drone/src/tests/acceptance/features/webUIFiles/fileDetails.feature:70
    Given the user has shared the folder "simple-folder" with the user "User Two" using the webUI              # WebUISharingContext::theUserSharesTheFileFolderWithTheUserUsingTheWebUI()
    And the user re-logs in as "user2" using the webUI                                                         # WebUILoginContext::theUserRelogsInUsingTheWebUI()
    When the user browses to the shared-with-you page                                                          # WebUIFilesContext::theUserBrowsesToTheSharedWithYouPage()
    Then the folder "simple-folder (2)" should be listed on the webUI                                          # WebUIFilesContext::theFileFolderShouldBeListedOnTheWebUI()
    When the user opens the file action menu of the folder "simple-folder (2)" in the webUI                    # WebUIFilesContext::theUserOpensTheFileActionMenuOfTheFolderInTheWebui()
    And the user clicks the details file action in the webUI                                                   # WebUIFilesContext::theUserClicksTheFileActionInTheWebui()
    Then the details dialog should be visible in the webUI                                                     # WebUIFilesContext::theDetailsDialogShouldBeVisibleInTheWebui()
    And the thumbnail should be visible in the details panel                                                   # WebUIFilesContext::theThumbnailShouldBeVisibleInTheDetailsPanel()

e.g. it happened just now in core: https://drone.owncloud.com/owncloud/core/12093/493
and it has happened sometimes in when running with encryption and/or object store (files_primary_s3) - those are apps that have some impact on the backend timing/performance...

GitMate.io thinks possibly related issues are #22485 (test), #31579 (test), #22492 (test), and #32143 (MinkSelenium2Driver recent change breaks webUI tests).
