[Bug] ContentViewRespondsWhenViewRemoved test fails on Catalyst

[rmarinho]

Description

The test ContentViewRespondsWhenViewRemoved in ContentViewTests.iOS.cs fails when running on Catalyst, but passes on iOS. This creates a gap in test coverage between platforms.

See: https://github.com/dotnet/maui/blob/d4eb91b9de1bb22bae7aad738ef0e13ac4eb41cd/src/Controls/tests/DeviceTests/Elements/ContentView/ContentViewTests.iOS.cs

On Catalyst, after removing the content and measuring, the size is not (0,0) as expected by the test.

Steps to Reproduce

1. Build and run MAUI DeviceTests targeting Catalyst.
2. Run ContentViewRespondsWhenViewRemoved test.
3. The test fails on Catalyst (but not on iOS).
