topItemCount zero value is ignored

[maksimkoniukhau]

Describe the bug

TopItemCount '0' value is ignored.
I'm updating topItemCount property dynamically depends on some conditions. When I provide any positive number it is working as expected (top items displayed), however zero is ignored (top items stay on previous value).
I believe zero should be acceptable value in order to remove top items if they were displaying at start.

Reproduction

CodePen link for reproduction

To Reproduce

Steps to reproduce the behavior:

1. Render component with topItemCount prop = 2.
2. Change topItemCount value to 0
3. topItemCount zero value is ignored

Expected behavior

When providing zero as a topItemCount value top items should disappear.
