Is VirtualScroll and Filtering finally working in Ionic 4?

#1

Does migrating from Ionic 3 to 4 make sense here?
Our app uses VirtualScroll for lists and allows filtering by substring.
In Ionic 3 this never really worked, to reproduce just scroll down and then filter.
The VirtualScroll list just goes all white instead of showing the filtered elements.
When scrolling manually in Chrome desktop it worked again but this is not good for production use.

Has anyone tried this in Ionic 4 successfully?
Thanks for any hints!
