1) The HSBar needs space in the combo box to be displayed.
Why Khaled decided to make it the size it is, or why it shows in the combobox rather than below it (or beside it in the case of the VSBar), I don't know.
2) Limit is not listed as a valid style for a combobox, therefore the fact that it does not limit the combo box, imo, is not a bug, but rather, an idea for a Feature Suggestion.
