Display issue with block-beta diagram

[rodcloutier]

Description

When I use a block-beta diagram with nested blocks and a block with a name longer than 2 characters, one of the block is not properly displayed

Steps to reproduce

The following code should display the issue

block-beta
columns 1
    base

    block
    columns 3
      a
      b
      abc
    end
    block
      block
        1
      end
      space
      3
    end

block-beta
columns 1
    base

    block
    columns 3
      a
      b
      abc
    end
    block
      block
        1
      end
      space
      3
    end
