"firstLineIndent" wrong document

[mxl123]

I see the notice

Any properties affecting text or paragraph styling, such as `firstLineIndent` will only apply when text is set with an `NSString`. If the text is set with an `NSAttributedString`, these properties will not apply.

and the "setText" method

if ([text isKindOfClass:[NSString class]]) {
    [self setText:text afterInheritingLabelAttributesAndConfiguringWithBlock:nil];
    return;
}

the "setText:afterInheritingLabelAttributesAndConfiguringWithBlock" call "setText" with a mutableAttributedString.

The document tell me to set text rather than NSAttributedString, then the "setText" call itself with NSAttributedString in any case
