Suffix icon behavior for undefined is inconsistent between components

[wctiger]

Reproduction link

Steps to reproduce

Check the suffix icon of Select and DatePicker in the provided example

What is expected?

specifying undefined in suffixIcon in all components should yield the same UI behavior - either displaying nothing or the default icon, but not both

What is actually happening?

specifying undefined in Select renders the default caret, and the same value in DatePicker is rendering nothing

[wctiger]

I think consistency is more important. Intuitively thinking, displaying the default icon makes sense
