With this combo set to a width of "100%" instead of an actual pixel value, it will be made, but then slowly keep getting wider.
I only do this because the text in the combo is localized, so I just max it out so no text is clipped when not in English. I can almost give it an actual width value, but would be nice to automatically max the width out.
Please, check if there are no paddings and margins settings for the combo div. As in this case, combo size can not correctly calculated.
Or just use fixed height.
