Incorrect textarea drawing without linebreaks

Hello,

I was struggling with creating a unit that can display multiline strings. I found that there are Inspectable and InspectorTextArea attributes. However, they behave really strange with word wrapping:

Here is the code for the custom class:

[Inspectable]
public class LongText
{
    [Inspectable]
    [InspectorTextArea]
    [InspectorWide]
    public string Text;
}
