Zoneless: Boston Marathon sample does not execute ranking logic automatically #3970

When running an Angular application with zoneless change detection, the Boston Marathon sample does not execute the ranking logic automatically.

The sample is expected to calculate and display the rankings without requiring additional user interaction. However, in a zoneless environment, the ranking logic is triggered only after interacting with the grid, for example by hovering over it.

This appears to be related to zoneless change detection. In a standard Zone.js environment, the same sample executes the ranking logic automatically.

I have created a sample that reproduces the behavior:
