Description

Issue18751Test fails on iOS and Mac because images loaded from remote URLs via data binding fail to render when tests are executed in CI environments.

Issue18896Test fails on Android because images loaded from remote URLs via data binding fail to render when tests are executed in CI environments.

In the affected samples, the Image control uses XAML binding:
<Image Source="{Binding ImageUrl}" />
During CI execution, the images are not rendered, which causes visual verification failures and screenshot mismatches in UI tests.

Steps to Reproduce

1. Run Issue18751Test on iOS or Mac, and Issue18896Test on Android.
2. Observe the rendered UI output.
