### Description

[ScrollIssue.zip](https://github.com/user-attachments/files/27100382/ScrollIssue.zip)

```xml

```

### Link to public reproduction project repository

_No response_

### Version with bug

10.0.50

### Is this a regression from previous behavior?

Not sure, did not test other versions

### Last version that worked well

Unknown/Other

### Affected platforms

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

### Affected platform versions

_No response_

### Did you find any workaround?

_No response_

### Relevant log output

```shell

```

Start by running the attached ScrollIssue.zip reproduction on iOS and inspect Styles.xaml, especially with the default styles removed. Compare the CollectionView and ScrollView behavior when attempting to scroll to the top; done means the reproduction reliably reaches the top as expected.
