      Problem Statement/Rationale

      Bad Compass UI performance when woking with documents containing large arrays.

      Steps to Reproduce

      • Create a document containing an array field with a couple thousand string elements:

      {{{}}

        _id: "test",

        arr_field: [

          "elt1", "elt2", ... "elt2000"  

        ]

      }

      • Open the document in Compass
      • Expand the array
      • Scroll to the last element and double-click the value to enter the element editing mode
      • The application UI freezes for significant amount of time (10s of seconds)
      • Same happens when clicking either "Cancel" or "Update" after the app finally unfreezes.

       Expected Results

      Application should not freeze.

      Actual Results

      Application freezes.
