This change looks wrong: the repaint rectangles shouldn't change as part of this
change.

That's what I thought but the fact is that the Y value changes because the size
of the paragraph above changes. We might decide not to change the comment in the
bug but I think it's safe.

You are right, we set the font size to 10 in this test so it looks like we have
an extra line of text before of the longer property names. I would still go
ahead with the renaming of this test as we understand the difference.
