I think we should close this and wait for a customer bug report.

I hope folio-testing or folio-snapshot-load would have well-populated inventories that I could play with to check that their scrolling behaviour is basically the same as that of the match editor, but I simply can't find a FOLIO instance with non-trivial inventory or user register. Guide me!

Well, I am not really seeing the https://folio-org.atlassian.net/browse/UIPER-83#icft=UIPER-83 problems now — are you?

I do still get the thing where if you scroll down a long way in one go, it takes a while for the rendering to catch up – which I believe is true of all the other FOLIO modules that virtualize lists – but I am no longer seeing the thing when thin skeletal lines are rendered. I wonder whether that was a transitory problem in stripes-components?

It's hard for me to verify this, as the thor system doesn't really have inventory and hosts only a few Users. And every single module on Snapshot has only a handful of records.

@Mike Taylor what is involved in this issue?
