After a few experiments, it seems to be tied to the Browser Option to use the default fonts I've picked or to use "Document specified fonts". If I go to my default fonts everything is fine. Solves a couple of other browser-related problems I've had too. I owe Charles a vote of thanks for making me test this.
And you too, Andrew :-)
