Less Parse Error: Variable Body that starts with `&`

Prettier 1.15.1 Playground link

--parser less

Input:

@just-text-type-input-selectors: &:not([type='file']):not([type='checkbox']):not([type='radio']):not([type='range']):not([type='hidden']);

Output:

SyntaxError: (postcss) CssSyntaxError Missed semicolon (1:34)
> 1 | @just-text-type-input-selectors: &:not([type='file']):not([type='checkbox']):not([type='radio']):not([type='range']):not([type='hidden']);
    |                                  ^
  2 | 

Expected behavior: The line should parse fine, since it is valid less syntax, and the less compiler parses this fine.

I checked out the postcss-less repo and tried reproducing the bug. They fixed it in 3.0.0. So please update your dependency.
