I have looked into and tested for the setFont issue for sizing editable 
ComboBox's in Aqua L&F. A non-editable ComboBox in Aqua does NOT increase the 
height of the text area of the ComboBox with larger fonts. 
Here is an image where I increased the button by 50px in height and width:

This seems to be Aqua specific because when tested in other L&F's like Metal, 
the text areas and buttons increase in height to accommodate larger text. 
Here's an image from Metal L&F:

Additionally, the button of the ComboBox in Aqua never changes size as it seems 
the button appearance is pre-determined by JRS values. Increasing the size of 
the arrowButton in Aqua takes up the space that the enlarged button should 
take, but the button will still appear small.
This screenshot shows the Aqua button triggering the dropdown list after 
clicking the blank space where the button should be stretched to:
