A null element inside array causes UI to hang with "Rendering results..."

Seen in Vulcan RC1

When attempting to view documents inside a bucket, the UI hangs with "Rendering results..." if one of my documents has an array containing a null value.

See attachments for initial find, and below for a minimal document that can reproduce:

{

  "test": [

    null

  ]

}

{

  "test": [

    1,

    null,

    3

  ]

}
