That is correct - then fixes itself again when I zoom in further.  (In
the instances that I tested.)

Ah, I thought it might have been something like that.  So pango is
actually picking a different font depending on the on-screen size of
the text?

To clarify: not just the text, but also the surrounding box and the
line near the top of the box disappear.  They don't return at any
out-er zoom level.
