Description

Grid with a lazy data provider can end up in an infinitie loop when expanded items are assigned after clearing the cache.

Expected outcome

Grid should not end up in an infinite loop

Minimal reproducible example

1. Modify dev/grid.html so that the data provider callback is executed in a timeout
2. Add a button which does the following:

grid.expandedItems = [{ name: '0' }];
grid.clearCache();

Steps to reproduce

Click the button on the dev page
