### Version with bug

9.0.40 SR4

### Is this a regression from previous behavior?

Not sure, did not test other versions

### Last version that worked well

_No response_

### Affected platforms

Android

### Affected platform versions

_No response_

### Did you find any workaround?

None that I know of other than removing it out of the ScrollView. Although if your page uses a RefreshView it must use a ScrollView to be functional.

### Relevant log output

```shell

```

Start with the MainPage.xaml reproduction in the issue and run the .NET MAUI app on Android with the Map inside a ScrollView. Trace the Android map control's sizing behavior, then verify that the map fills the screen inside the ScrollView while the reported RefreshView use case remains possible.
