Description

### Description

On the Windows platform, when a CollectionView is placed inside a RefreshView, and a button is placed in the FooterTemplate, setting IsLoading = true (which triggers IsRefreshing) causes the RefreshCommand to execute multiple times instead of once.

This leads to multiple refresh executions and eventually results in an application crash.

This issue is not reproduced on Android or iOS.

### Steps to Reproduce

1.Create a RefreshView containing a CollectionView.
2.Add a Button inside the FooterTemplate of the CollectionView.
3.In the button click handler, set IsLoading = true.
4.Observe that the RefreshCommand executes multiple times on Windows.

Research direction

Start by running the provided CollectionViewScrollingRefreshBug sample and reproducing the issue with a RefreshView, CollectionView footer Button, and IsLoading set to true on Windows. Trace the RefreshCommand execution path and compare it with Android or iOS behavior; done means the command executes once and the sample no longer crashes.
