[XeTeX] x:rotate conundrum

[Stephen Moye]

I thought I understood how x:rotate works, but I apparently don't, not completely. The following code snippet demonstrates the problem. The stuff that follows the rotated bit seems to disappear -- I know it doesn't really, but I can't find it, which amounts to the same thing... :>} What am I missing? I'm using 0.997-dev.
