From https://bugs.eclipse.org/bugs/show_bug.cgi?id=579028#c7:

> When an editor loses focus and then gains it again, only the "blinking OS caret" 
> is drawn, but the other virtual carets are not updated/drawn until the caret 
> moves. This is because Composite.setFocus() -> ... -> Caret.setFocus() doesn't 
> know of extra carets, and thus only shows one caret.
> A remedy would be to add an implementation for StyledText.setFocus() like this:
>    @Override
>    public boolean setFocus() {
>    	boolean b = super.setFocus();
>    	setCaretLocations();
>    	return b;
>    }
>
> This takes care of the drawing of the extra carets.
