Markdown Viewer doesn't render any spaces in Unity 2023.1 or later

It looks like this is due to GUIStyle.CalcSize() not counting the trailing space. LayoutBuilder.AddWord() calls CalcSize() on a string with a trailing space for each word. But I'm not sure why this used to work. Did the CalcSize() implementation change?

It looks like the implementation of CalcSize() has changed in Unity.

I have attached a quick work around as a pull request to this issue. However, it is not clear to me whether this is an intentional change in behaviour or a bug, given 2023.2+ are all in beta.

So I am reluctant to merge this in (or actually write a better fix and not hardcode the values) right now. What do you reckon?

Ah OK, looks like it was a bug with Unity. Maybe I should have checked there first :)

This has been fixed in 2023.3.

Actually, I'm going to keep this issue open for now to keep track of it until Unity actually release the fix.
