Reproduction

https://stackblitz.com/github/empty-god/scroll-test

Steps to reproduce:

  1. Click on any item in the list, and scroll to get new items
  2. You should see the non-selected items highlighted, in no specific order

Expected Behavior

The list should continue scrolling with no further highlight changes without a new click.

Actual Behavior

The list seems to select a similarly placed item instead of referencing the correct variable in selection.

Environment

  • Angular: 8.2.13
  • CDK/Material: 8.2.3
  • Browser(s): Chrome 79.0.3945.79
  • Operating System (e.g. Windows, macOS, Ubuntu): Catalina 10.14.6

Notes

This seems to be fixed when you use templateCacheSize is set to 0.
