Expanding rows in a virtualized table will cause it to scroll to top

dominictwlee opened this issue · comments

Describe the bug

When implementing expandable rows in a virtualized table, toggling an expandable row will immediately cause the table to scroll to top regardless of where the the current scroll offset is.

Your minimal, reproducible example

https://stackblitz.com/edit/tanstack-virtual-xdmecx?file=src%2FApp.svelte

Steps to reproduce

  1. Scroll down table.
  2. Toggle on/off an expandable row.
  3. Table will immediately scroll to top.

Expected behavior

I expect to be able to toggle an expandable row and still be able to see it in it's current scroll position. Instead, It scrolls all the way to the top.

Yeah it seems that anything that causes the count option to change will cause an automatic scroll to the top

im having the same issue. Are there any workaround or fixes?
