[Android] WebView Height Continuously Increases on Pixel 5, API 33

### Description

When using a WebView inside a custom Grid control on Android (Pixel 5, API 33), the height of the control continuously increases over time. This behavior is not observed on other platforms like iOS or Windows.

**Note**: The issue is specifically reproduced when the layout structure is Border → Grid → WebView. If the Border is removed and the structure becomes Grid → WebView, the issue no longer occurs. This suggests the Border may be contributing to the layout instability.

### Steps to Reproduce

1. Create a custom view inheriting from Grid.
2. Add a WebView with a fallback HTML source.
3. Embed the WebView inside a Grid, which is wrapped in a Border, and place that inside the root Grid.
4. Run the app on Android (Pixel 5, API 33).
5. Observe the control height increasing continuously.

#### Expected Behavior
The WebView should maintain a consistent height and render the fallback HTML without affecting layout dimensions.

#### Actual Behavior
The control's height keeps growing, leading to layout overflow and rendering issues.

#### Device Information
• **Device**: Pixel 5
• **OS Version**: Android 13 (API 33)
• **.NET MAUI Version**: 9.0.111,9.0.82
• **Platform**: Android

Code Snippet:

```
public class CustomView : Grid
{
public CustomView()
{
var border = new Border() { Stroke = Colors.Red };
var grid = new Grid();
var webview = new WebView();
var fallbackHtml = @"

";
webview.Source = new HtmlWebViewSource { Html = fallbackHtml };
grid.RowDefinitions.Add(new RowDefinition { Height = GridLength.Star });
border.Content = grid;
grid.Children.Add(webview);
Grid.SetRow(webview, 0);
this.Children.Add(border);
}
}
```

Start with IssueSample.zip and reproduce the layout on Android 13/API 33 using the Pixel 5 setup described. Compare the Border → Grid → WebView structure with the Border-removed version while observing layout measurements; done means the WebView keeps a stable height and renders the fallback HTML without layout overflow.
