fix: minimalist-ios-tapbar.yaml

[mxilievski]

This is a temporary workaround rather than a comprehensive fix. While it significantly improves the current situation, it's not production-ready and shouldn't be merged as-is. I'm sharing this to provide guidance for someone who can implement a proper solution, and to offer an interim option for those who need immediate relief while we develop the definitive fix.
