Research direction
Investigate the NumberBox.Value setter in Uno source for potential infinite recursion. Compare with WinUI behavior and implement a guard if necessary. Add unit tests to cover the scenario. Refer to the WinUI issue mentioned in the description (image). Look for similar patterns in other controls that may have been fixed.
