Steps to reproduce

nzSelect的option的nzValue的值为数组，ngModel绑定的值也为数组，自定义compareWith函数，当数组中的第一个值相等时，使对应的option被选中。但实际默认选项确未被选中。但当我把绑定的值改为对象时，却可以正常选中，数组就不行

What is expected?

Translation of this issue:

When the value bound to the nzSelect component is an array, the default value is not selected.

Steps to reproduce

The value of nzValue of nzSelect's option is an array, and the value of ngModel binding is also an array. Custom compareWith function, when the first value in the array is equal, the corresponding option is selected. However, the actual default options are not selected. But when I change the value of the binding to an object, it can be selected normally, and the array will not work.

What is expected?

When the value bound to the nzSelect component is an array, the option that conforms to the compareWith function is selected by default.

What is actually happening?

The option to match the compareWith function is not selected
