Description

Describe the bug

I'm doing some POC to check if I'll be able to render a larger list and I face some issues with the current approach you use by setting the height of the parent element to create the scrollable area. If the list size is long it could beat the max height value which is:

Firefox: 33554400px
Chrome:  33554428px

https://stackoverflow.com/questions/16637530/whats-the-maximum-pixel-value-of-css-width-and-height-properties

In that way is impossible to keep scrolling until the end of the list

Your minimal, reproducible example

Steps to reproduce
  • Create a list with 1677723 items and each item should have 20px
  • Cannot scroll to see the last item
Expected behavior
  • Create a list with 1677723 items and each item should have 20px
  • Be able to see the last item

Research direction

Start with the linked CodeSandbox minimal reproduction and verify the failure using a list of 1,677,723 items at 20px each in Chrome. Trace how the virtualized list creates its scrollable parent and determine how the browser height limit is handled. Done means the last item is reachable in the reproduction without breaking normal scrolling.
