    Description

      When replacing items on a StackView that has both popExit and replaceExit set, running the application (both debug and release builds) in the debugger results in the following:

      HEAP: Free Heap block 1d3e1a80 modified at 1d3e1ac8 after it was freed

      Running without debugger seems fine.

      Attached a minimal example that reproduces it once the switch to 'red' is made.
