DataTable: Multiple sorting with Date field as first sort

[BearsPunch]

Describe the bug

The same issue what Primereact had. link to the issue
DataTable doesn't sort dates correctly. Two completely identical dates are different for table and this bug causes another bug, when you try to sort multiple columns and use date column as primary. Every next column with lower sort priority after date column will not be sorted correctly.
Added stackblitz with example. Just select Year column as primary sort and try to sort Color column as second column. You will not be able to sort cars with date "21.05.1995" by color alphabetically, because table see these dates as different.
As I see, issue in function

multisortField(data1, data2, multiSortMeta, index) {
...
if (value1 == value2)
}

Dates should be compared in another way

Steps to reproduce the behavior
