bug(DragDrop): Uncaught TypeError: Cannot read properties of null (reading 'removeEventListener') when dragging and dropping items synced with API

[YugasVasyl]

Reproduction

I have found the similar (same?) unresolved issue here
#18628
with reproduction example.
In my case drag&drop synced with BE via API, so it's hard to reproduce, but sometimes when user drags and drops items fast it errors with
Uncaught TypeError: Cannot read properties of null (reading 'removeEventListener')
It doesn't affect functionality, but I don't want to see those errors in the console and Sentry.

Environment

• Angular: 12.2.2
• CDK/Material: 12.2.2
