Nested Yard Types don't work in hovers

[olbrich]

When I document a variable like.

  # @type [Array<String>]
  array_of_arrays = [
    [
      'foo',
      'bar'
    ]
  ]

I get a hover like...

If I change it to...

  # @type [Array<Array<String>>]
  array_of_arrays = [
    [
      'foo',
      'bar'
    ]
  ]

I would expect to get an Array<Array<String>> in the hover
