Moving the caret and then using the suggestion I made in comment 12 will update the focus accordingly. The latest patch appears to do that.

That will and should do nothing.

How does it not work?

I don't know how the specifics of how the caret is moved. I only know that the caret is moved and the focus updated to match (this is done in nsSelectMoveScrollCommand::DoCommandBrowseWithCaretOn)

The document.activeElement (of the document the button is in) should be set to that button. The window will not be made frontmost unless the raise flag is passed to SetFocus.
