Current behavior:

My list is a nested object.
First loop: group of groups
Second loop: users of group

I need virtualScroll because there may be many many users.

But it doesn't work properly. There are inconsistent white spaces between users as in this screenshot:

Expected behavior:

Could be nice to use virtualScroll inside another loop.

Steps to reproduce:

Here is a plunker where I recreated the situation (in the home-page component):

Scrolling up and down makes visible that performance issue

At the moment there are a lot of problems with virtual scroll, maybe anyone can suggest alternative?

@FrancescoMussi at the moment it's totally broken :) though I see some issues being resolved in the milestones

Ok thanks. Just wondering if it is on their tasks list or has been forgotten.
