UITextView lineHeightMultiple Clips Top, first line, of Text

In iOS 8, I have a vanilla

UITextView

that clips the top of the 1st line when a

lineHeightMultiple

is applied to it's

NSMutableParagraphStyle

, see image below:

It appears as though

lineHeightMultiple

affects the 1st line of text in addition to subsequent lines.

Setting

clipsToBounds = false

on the

UITextView

will at least enable the clipped part to show, but you can see from the image below that now the top part of the text is obviously above it's frame:

I can fix this by just setting the top constraint on the offending

UITextView

to compensate for

clipsToBounds = false

but that feels like a hack to me.

I have also tried using a

WKWebView

for the offending text, and just setting the css

line-height

property, and that works just fine. There must simply be something I am missing when it comes to UITextView though.

Additionally, setting

lineSpacing

on the paragraph style to less than 0 has no affect, per the docs:

The distance in points between the bottom of one line fragment 
and the top of the next. 

**This value is always nonnegative.** 

This value is included in the line fragment heights in the 
layout manager.

I have also tried setting the

contentInset

of the

UITextView

as well as using a system font, both had not affect.

My sample code for this setup follows:

let text = "THIS IS A MULTILINE RUN OF TEXT" 

let font = UIFont(name: "MyFontName", size: 31.0)!
// let font = UIFont.systemFontOfSize(31.0)

let paragraph = NSMutableParagraphStyle() 
paragraph.lineHeightMultiple = 0.75 
paragraph.alignment = NSTextAlignment.Center 

let attributes = [ NSParagraphStyleAttributeName: paragraph, NSFontAttributeName: font ]

titleView.attributedText = NSAttributedString(string: text, attributes: attributes) 
// titleView.contentInset = UIEdgeInsets(top: 50.0, left: 0.0, bottom: 0.0, right: 0.0)
titleView.clipsToBounds = false

Has anyone encountered this and overcome or is the top constraint hack the only way to go?
