Description

When using No cache strategy (templateCacheSize: 0) for *cdkVirtualFor with element (as image), elements of list glitch while scrolling. Seems like cdkVirtualFor incorrectly init/reinit or reuse instances of listed elements.

When using tag instead of no bug detected.

Reproduction

Steps to reproduce:

1. Create list of 100 elements, use with image link data.
2. Scroll

Expected Behavior

Smooth scrolling, correct reusing/reinit of list elements, no content replacing.

Actual Behavior

Scrolling is not smooth (end sometimes end / start of list is unreachable), elements in list are replaced by content of sibling.
