fix: schedule height update for async element updates

[ugur-vaadin]

Description

It is possible that the height calculations are not complete for all the elements when the positioning in the virtualizer occurs. This is reproducible not only with a grid, but with any component that uses a virtualizer. In order to prevent the incorrect positioning and overlapping of items, this PR adds one cycle of additional measurements for async height updates. This does not seem do cause any flickers, weird scrolling behaviour, or performance issues.

Fixes #9077
