When you add truncation to a textbox and set max lines it will not work properly if your text has paragraph spacing >0 and set the height as “hug contents”. As a result, the text will overflow the text box.
Unclear about what the desired behavior should be here as different options have their tradeoffs. But I definitely think text should not be overflowing its textbox.
I think there should ideally be an option to truncate after a pixel height and not just number of lines. As most of the time I just want to limit the height or length of my text box.
