Issue Details
In the issue, mentioned two tests are failed
BackButtonBehavior_IsEnabled_False_BackButtonDoesNotNavigate
The test failed due to PR #28734. The PR included a fix for the BackButton IsEnabled issue, but it resolves the issue on iOS 18, not on iOS 26. Further improvements are needed for iOS26, which was added in the PR.
Root Cause
On iOS 26, the Shell back button test failed because tapping the back button while BackButtonBehavior.IsEnabled was false left the Shell renderer in a pending back-navigation state. After the button was enabled again, the next back tap was still blocked, which caused the test to time out instead of returning to the main page.
Description of Change
The fix clears the pending back-navigation flag when a disabled back tap is ignored, so back navigation works correctly once the button is re-enabled.
BackButtonBehavior_IsVisible_False_ProgrammaticNavStillWorks
Above test fail related to base snapshot, which was addressed in PR #34617
Issues Fixed
Fixes #34771
