Plunkr Case (Bug Reports)
Expected code is descripted at "Expected behavior".

Current behavior
When label text is too long at Checkbox and Radiobutton, label text is made linefeed.
At then, Radiobutton label's start position is different to Checkbox.

• At checkbox
  

• At Radiobutton
  

Expected behavior
Radiobutton label's style display:inline-block generates this behavior.
By eliminating this, it will be solved.
