BBCode-buttons in Opera 9.1

In Opera 9.1, when no text is marked in the posting-textarea and you push one of the BBCode-buttons they get inserted, but the closing tag stays marked... In IE (and probably Firefox) the cursor instead ends up between the two tags, which I think is the intended behavior...

See screenshot to see what it looks like. (it is not easy to see because I switced programt to the screenshot-program, but if you look closely you can see that it is marked...)
