When the size attribute of select tag has 2 or 3. it's working properly. it works like 'size=4'. Firefox is working with little regard to size=2/3. As my investigation, this is because minSize in RenderListBox.cpp is limited to 4. I can guess there has been a historical reason there with the following comment. but I doubt if it's still valid now. > // The minSize constant was originally defined to render scrollbars correctly > // This might vary for different platforms. I couldn't find any problem for Macport running on Marvericks and Lion. The scrollbar shows up and automatically hide after few seconds on the platforms. And also I don't think GTK port has any problem for size=2/3, though GTK+ 3.0 doesn't paint scrollbar for such a short list, but it presents more lists remained by using up/down arrow indicators. I propose to change minSize from 4 to 2.
