Using multiple spaces in tagcloud does not reflect the Nested Spaces feature while using 1 space does.

Using multiple spaces in tagcloud does not reflect the Nested Spaces feature while using 1 space does.

To reproduce :

• Reproduce a 2 level of nested pages documents

  1 (tag 1)
  1 > 1 (tag 11)
  2 (tag 2)
  2 > 1  (tag 21)
  

• Set a tagcloud "spaces" to '1','2'
• Set a tagcloud "space" to '1'

Expected :

• Both behaviour for 1 space or multiple spaces is the same when displaying tags = all tags from nested pages are displayed
