Virtualizer (@lit-labs/virtualizer)

Description

When layoutComplete is accessed multiple times for a given layout cycle, the same promise should be returned. It is not.

Reproduction

1. Run this Playground example

Expected result: Console should log SAME? true
Actual result: Logs SAME? false

Workaround

If you can, avoid accessing layoutComplete multiple times within a given layout cycle

Is this a regression?

No or unsure. This never worked, or I haven't tried before.
