Unexpected event icon

### What Happened?

Calendar draws a car icon next to the event when its title contains "car".

The Brazilian Carnival does have cars, but it's not the same kind! 🤣

### Steps to Reproduce

1. Add an event with the title "Carnival" or any other word that contains "car" in it.

### Expected Behavior

Maybe it should only match the whole word "car"? e.g. "Wash my car"
