Ever since upgrading to 2.1, I've noticed that my previous semantically coded tags for italic and bold are doing strange things. For example, 'em' results in bold text on screen and 'strong' becomes bold, all upper case.
Weirder still, if I revert to non-semantic 'b' or 'i' the formatting holds for a period of time and then reverts to the original semantic tags (a neat feature if the semantic tags worked as they should).
Any thoughts on what I'm doing wrong?
Thanks very much.
