nz-table nzVirtualScroll last item rendered is wrong
See original GitHub issueReproduction link
https://stackblitz.com/edit/nz-virtual-scroll-index-issue?file=src%2Fapp%2Fapp.component.ts
Steps to reproduce
Quickly scroll to the bottom of the table and there is a high chance (30% or more) that the last index is not 359 (last item).
If it is 359, scroll to top and then to bottom again
What is expected?
the last index item should be 359
What is actually happening?
The last index is not 359
| Environment | Info |
|---|---|
| ng-zorro-antd | 8.3.0 |
| Browser | Chrome Version 76.0.3809.132 |
If the listOfData length is 20000 instead of 360, the bug does not occur.
A workaround to this bug is to return undefined instead of data.index in function trackByIndex
