  The <admin-task-runs-sk> custom element declaration. Displays a table with details about each
  completed and pending admin task, and allows the user to delete pending tasks if applicable.

  Attributes:
    url: POST URI to request tasks, e.g. "/_/get_recreate_page_sets_tasks". Must be set.
    deleteUrl: POST URI to delete a task, e.g. "/_/delete_recreate_page_sets_task". Must be set.
    redoUrl: POST URI to redo a task, e.g. "/_/redo_recreate_page_sets_task". Must be set.
    taskType: Type of task, e.g. "RecreatePageSets". Must be set.
    defaultSize: The number of tasks to show per page, default 10.
    constrainByUser: Whether to show only tasks created by the logged-in user initially, default
      false.
    myRunsConstrainText: Button text to constrain by user, default "View only my runs".
    everyonesRunsConstrainText: Button text to disable constraining by user, default "View
      everyone's runs".
    constrainByTestRun: Whether to show only non-test tasks, default true. Test tasks are those that
      use the "Dummy1k" page sets.
    nonTestRunsConstrainText: Button text to constrain to non-test tasks, default "Exclude test
      runs".
    testRunsConstrainText: Button text to disable constraining by test tasks, default "Include test
      runs".

  Events:
    None.

  Methods:
    reload: queries for updated information on tasks.
    resetPagination: Moves to the first page of tasks.
    constrainRunsByUser: Toggles constrainByUser and reloads the appropriate data.
    constrainTestRuns: Toggles constrainByTestRun and reloads the appropriate data.
