Nested shortcode indenting is slightly off

[shortcode1]
  [shortcode2]
    [shortcode3]
      [shortcode4]
        [shortcode5]
          asdf
        [/shortcode5]
      [/shortcode4]
    [/shortcode3]
  [/shortcode2]
[/shortcode1]

If you type that in text view then switch to visual, it will reformat the indents to:

[shortcode1]
 [shortcode2]
    [shortcode3]
     [shortcode4]
        [shortcode5]
        asdf
        [/shortcode5]
     [/shortcode4]
    [/shortcode3]
 [/shortcode2]
[/shortcode1]
