Collection View in MAUI iOS, Android scrolling erratically.

### Description

Hi,
I am creating an app where I am using collection views with complex item templates and fetching data from API.
But the list after loading scrolls erratically and freezes sometimes. Any suggestions or workarounds to make the scroll animation more smooth?

### Steps to Reproduce

1. Create a collection view.
2. Fetch data from API.
3. Populate the list and see the scroll behaviour.

### Version with bug

6.0.400 (current)

### Last version that worked well

Unknown/Other

### Affected platforms

iOS, Android, I was *not* able test on other platforms

### Affected platform versions

iOS 15, Android API 30, 31

### Did you find any workaround?

Not yet.

### Relevant log output

```shell
Did not find any significant output
```

Start by reproducing the CollectionView behavior using the listed steps on iOS 15 and Android API 30 or 31, with data fetched from an API and complex item templates. Compare scrolling before and after loading; done means the list scrolls smoothly without erratic movement or freezes.
