Hi all, news for this bug?

I'm having the same issue. Is it even possible to get *cdkVirtualFor to render something in SSR? Shouldn't it at least be possible to prerender an item list which has a fixed item size on every viewport width?

As per the code CDK virtual scroll will not support SSR, did I miss spotting this anywhere on the docs page? If not why it is not explicitly mentioned anywhere?
