Less Parse Error css-varvalueexpected for Variable Body that starts with `&`

[fabb]

This is valid less (you can check with ):

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

input {
	@{just-text-type-input-selectors} {
		color: blue;
	}
}

It should be parsed correctly, but VSCode shows the error css-varvalueexpected.
